This is MyProxy v5.0 4 Dec 2009.
This version should be protocol compatible with all versions since v0.2.
Binary compatibility of the C API is not guaranteed between releases.

Version History
---------------
v5.0 4 Dec 2009
  - add Globus Usage Metrics to the myproxy-server
  - in myproxy-server, atomically update credential files and avoid
    unnecessary file copies; NOTE API CHANGE: myproxy_creds_store()
    now moves file to the repository, rather than copying it
  - add myproxy-server.config request_size_limit parameter to control
    myproxy-server network limits, and fix network limit handling to
    apply only to myproxy-server (not clients), so clients can handle
    large X509_CERT_DIR contents
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6889)
  - include extendedKeyUsage=clientAuth in EECs by default per GFD.125
  - add myproxy-logon/myproxy-get-trustroots -b option to allow
    bootstrapping CA trust even when X509_CERT_DIR exists
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6886)
  - myproxy-logon -T / myproxy-get-trustroots fixes/improvements:
    - when cleaning bad CRLs, also remove any CRLs we can't parse
    - when recovering from CRL errors, allow anonymous authentication
      on second attempt, just like first attempt
    - when bootstrapping, restrict CA trust to only the one
      certificate subject needed, rather than a wildcard

v4.9 2 Nov 2009
  - fix support for "check_multiple_credentials true" in
    myproxy-server.config, disabled since v4.4
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6878);
    changes include:
    - limit check_multiple_credentials functionality to GET requests
      (myproxy-logon) only
    - in authorization failures, give underlying error message rather
      than check_multiple_credentials unique error message
    - add myproxy-test cases for check_multiple_credentials and
      myproxy-admin-query

v4.8 10 Sep 2009
  - add myproxy-server.config proxy_extfile and proxy_extapp options
    for including custom certificate extensions in proxy certificates
    issued from the MyProxy repository (analogous to
    certificate_extfile and certificate_extapp for the CA module);
    requires GT 4.2.0 libraries (or later)
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6786)
  - look for VOMS header files in include/voms directory for
    compatibility with Fedora's VOMS package
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6847)
  - exit with an error message when --voms and -o - are used together
    in myproxy-logon
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6807)
  - fix a memory error in myproxy-info/myproxy-destroy error handling
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6849)
  - check myproxy-server.config lines for correct number of arguments
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6852)

v4.7 6 May 2009
  - in myproxy-get-trustroots and myproxy-logon -T, update files
    atomically (using rename) rather than overwriting
  - add myproxy-get-trustroots.cron example for keeping
    /etc/grid-security/certificates up-to-date
  - support linking against flavored VOMS libraries
  - fix "self-authorization" check for CA requests
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6713)
  - check certificate requests and issued certificates in the CA:
    (http://bugzilla.globus.org/globus/show_bug.cgi?id=6648)
    - add certificate_request_checker and certificate_issuer_checker
      options in myproxy-server.config for specifying call-outs
      before and after the MyProxy CA signs certificates
    - example myproxy-cert-checker and myproxy-certreq-checker
      call-outs are installed in $GLOBUS_LOCATION/share/myproxy
    - only accept RSA keys in certificate requests
    - don't allow RSA exponents < 65537
    - add min_keylen option in myproxy-server.config for specifying a
      minimum allowed RSA key length
  - add syslog_facility option in myproxy-server.config to configure
    the myproxy-server to log to the specified syslog facility; the
    default is the "daemon" facility
    (http://bugzilla.globus.org/globus/show_bug.cgi?id=6717)
  - added an example in myproxy-accepted-credentials-mapapp
    of how to ban users (http://myproxy.ncsa.uiuc.edu/blacklist.html)
  - added myproxy-admin-query -o option to query by owner DN
  - replace fixed-length buffer in read_data_file() (credential
    repository file parser) with dynamically-sized buffer to support
    credentials with policies longer than 511 characters
    (http://bugzilla.globus.org/globus/show_bug.cgi?id=6723)
  - added certificate_serial_skip in myproxy-server.config to support
    staggered serial numbers across multiple CA instances
  - added certificate_issuer_hashalg in myproxy-server.config to
    configure the MyProxy CA to issue certificates using SHA-2 hash
    algorithms (SHA-224, SHA-256, SHA-384, SHA-512) rather than SHA-1
    (the default). Requires OpenSSL 0.9.8 or later.

v4.6 25 Mar 2009
  - add myproxy-get-trustroots command to download trusted CA
    certificates without client-side authentication
    (http://bugzilla.globus.org/globus/show_bug.cgi?id=5899)
  - add sasl_mech, sasl_serverFQDN, and sasl_user_realm
    options to myproxy-server.config
  - include certificate subject in myproxy-admin-adduser output
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6324)
  - handle error response message from myproxy-server during delegation
    (http://bugzilla.ncsa.uiuc.edu/show_bug.cgi?id=359)

v4.5 12 Feb 2009
  - in myproxy-server, disallow release of a credential based only on
    authentication with a client credential of the same subject (i.e.,
    self-renewal) unless "allow_self_authorization true" is specified
    in myproxy-server.config
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6630)
  - fix myproxy-logon --voms interaction with --out option
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6612)
  - implement stricter checks on myproxy-server storage directory
    security using Safefile's safe_is_path_trusted_r()
    (http://pages.cs.wisc.edu/~kupsch/safefile/); for now, these
    checks result in WARNING messages rather than errors
  - added myproxy-server --portfile option, useful when binding to a
    random available port via myproxy-server --port 0
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6623)

v4.4 12 Dec 2008
  - allow $MYPROXY_SERVER and -s command-line options to be a
    comma-separated list of hostnames to try to connect to
  - in myproxy-server, fail on startup or reconfig with an "unsafe
    policy" error if a policy of trusted_retrievers "*" is specified
    without also specifying a restrictive default_trusted_retrievers
    policy, to avoid an unsafe policy that could release credentials
    to any client without additional authentication.
  - in myproxy-server, log info for the received client request before
    the authorization check, so we have the request info for
    troubleshooting purposes even if the request is denied.
  - in myproxy-server, fail on startup if PAM, SASL, or OCSP is
    configured in myproxy-server.config but the needed libraries are
    not linked in
  - fix problem with OpenSSL engine (for HSM support) being shutdown
    on child process failures
  - fix bug when issuing certificates with subject containing "//"
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6488)
  - add support for multiple --voms options to myproxy-init/logon
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6436)
  - added myproxy-info --credname option
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6561)
  - for myproxy-logon -T, bootstrap the trusted certificates directory
    atomically (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6432)
  - for myproxy-logon --voms, request the correct proxy type from
    voms-proxy-init
  - added example myproxy-revoke and myproxy-crl.cron scripts for
    revoking certificates issued by the MyProxy CA and generating CRLs
  - added max_cred_lifetime option in myproxy-server.config to limit
    the lifetime of credentials stored in the repository

v4.3 2 Sep 2008
  - improve MyProxy CA error message on incorrect passphrase.
    specifically, in myproxy-server, if passphrase in the request is
    non-empty, fail immediately if it can't be verified, rather than
    trying other methods; this forces other authentication methods
    (SASL, renewal) to send an empty passphrase (which current clients
    do by default), but it results in a better error message in the
    common case when an incorrect passphrase is given.  also stop
    appending "invalid pass phrase" to the more specific error
    message from PAM or OpenSSL.
  - fix -m command-line option for myproxy-init and myproxy-logon
  - fix myproxy-init --voms with GT_PROXY_MODE="old"
  - in myproxy-init --voms, use voms-proxy-init -vomslife so VOMS AC
    lifetime matches proxy lifetime
  - if myproxy-init --local_proxy and --voms options are used
    together, only call voms-proxy-init once, and use that proxy to
    create the local proxy (via grid-proxy-init)
  - add a default timeout of 120 seconds for myproxy-server child
    processes to service requests before aborting, customizable via
    the myproxy-server.config request_timeout parameter
  - in myproxy-server, read incoming messages up to 1MB maximum to
    avoid memory exhaustion under heavy load
  - on myproxy-server startup, perform more sanity checks before fork
    to become daemon so exit status of original process is set to 1 on
    errors (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=6325)
  - in myproxy-server, don't re-read config file automatically on
    changes (i.e., undo change in v4.2); instead, re-read on SIGHUP
    (http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=5627)
  - add reconfig method to etc.init.d.myproxy
  - make myproxy-admin-adduser less verbose by only showing the output
    of grid-cert-request on errors
  - added myproxy-admin-adduser -p option for specifying the CA
    private key password using openssl format (see the PASS PHRASE
    ARGUMENTS section in the openssl(1) man page)
  - associate "Connection from xxx.xxx.xxx.xxx" syslog message with
    child pid so it matches up with other syslog messages for that
    client

v4.2 10 Jan 2008
  - add support for $GT_PROXY_MODE="rfc" in myproxy-init
  - in the myproxy-server, no longer default to issuing a "legacy
    globus proxy" from an end-entity certificate; instead, issue
    the default proxy type according to the GSI library version
  - drop support for $GT_PROXY_MODE="old" in myproxy-logon;
    however, myproxy-init still supports $GT_PROXY_MODE="old"
  - in myproxy-server, re-read config file automatically on changes
  - fixes for newer OpenSSL versions used in GT 4.2
  - fixes for MIT Kerberos 1.6 support (via SASL)

v4.1 10 Sep 2007
  - in myproxy-server, listen on $MYPROXY_SERVER_PORT if defined
  - for myproxy-logon/myproxy-retrieve -T, fix handling of zero length
    files and process only regular files (not subdirectories)

v4.0 11 Jul 2007
  - add myproxy-server-setup script for simple server install
  - fix myproxy-logon/myproxy-retrieve -T bug that caused trust
    bootstrap to fail when no certificates directory exists
  - add myproxy-admin-load-credential --retrieve_key and
    --retrievable_by_cert options
  - add myproxy-admin-addservice for distributing host/service
    credentials

v3.9 12 Jun 2007
  - update myproxy-logon/myproxy-retrieve -T behavior:
    - if no certificates directory exists, install the
      myproxy-server's CA certificate to bootstrap trust
    - if authentication to the myproxy-server fails due to a CRL
      error, remove problematic CRL file(s) and retry
    - if running as root, store trust roots in
      /etc/grid-security/certificates rather than
      ~root/.globus/certificates and credentials in
      /etc/grid-security/hostcert.pem/hostkey.pem
  - add --voms options to myproxy-init and myproxy-logon to add VOMS
    attributes, analogous to voms-proxy-init -voms; requires
    voms-proxy-init to be installed and configured
  - add myproxy-admin-query --config option

v3.8 13 Apr 2007
  - drop support for Globus Toolkit versions 3.0 and 2.4

    with additional diagnostics written to the server log
  - fix configure check for OCSP functions in OpenSSL for enabling
    OCSP support
  - for --help, --usage, and --version options, exit with status 0
    after printing help/usage/version information
  - add OpenSSL Engine support in the MyProxy CA to enable the use of
    hardware tokens via new myproxy-server.config
    certificate_openssl_engine options
  - check if client authenticates with a limited proxy, and if so,
    only allow the client to obtain another limited proxy, unless
    ignore_globus_limited_proxy_flag is set in myproxy-server.config
  - optionally store all certificates issued by the MyProxy CA in a
    directory via the certificate_out_dir myproxy-server.config option

v3.7 12 Dec 2006
  - fix handling of usernames containing '/', '-', and '.' characters;
    note this required a change to the myproxy-server repository
    format, so credential data files written by a new myproxy-server
    won't be readable by an older myproxy-server
  - verify that credentials in the myproxy-server repository are still
    valid (i.e., not revoked) before performing delegation
  - added myproxy-admin-query --invalid option for listing, locking,
    or removing invalid credentials from repository
  - optionally check OCSP status of stored credentials before
    performing delegation via myproxy-server.config ocsp settings;
    requires GT 3.2 (OpenSSL 0.9.7) or later
  - update etc.init.d.myproxy script to use pidfile to locate server
    to stop (rather than searching ps output), include a restart
    option, and exit with error if $GLOBUS_LOCATION isn't set
  - if the myproxy-server hostname given by $MYPROXY_SERVER or the -s
    option resolves to multiple IP addresses, clients will connect to
    each address until a connection is established or all fail

v3.6 10 Aug 2006
  - support credential renewal via the MyProxy CA using
    myproxy-server.config authorized_renewers/default_renewers options
  - provide an access control list for storing credentials via the
    myproxy-server.config accepted_credentials_mapfile option
  - fix insecure temporary file handling in myproxy-admin-adduser
  - fix insecure input handling in myproxy-get-delegation.cgi example
  - support VOMS attributes in myproxy-server.config policies
  - in CA, issue certificates valid starting 5 minutes in the past to
    account for possible clock skew between hosts
  - add check_multiple_credentials option in myproxy-server.config
    to allow clients to retrieve a credential for a given username
    even if the associated "credential name" isn't provided (via
    myproxy-logon --credname)

v3.5 14 Mar 2006
  - dropped support for certificate_issuer option in
    myproxy-server.config; use certificate_issuer_cert instead
  - added myproxy_accept_delegation_ex() to retrieve credentials to a
    buffer rather than a file

    output via '-o -' option; also added --quiet option
  - added myproxy-logon --no_credentials option to authenticate
    without retrieving credentials
  - added certificate_mapapp call-out for mapping usernames to
    certificate subject distinguished names for the CA module
  - added certificate_extfile and certificate_extapp (call-out) for
    setting extensions in certificates issued by CA module
  - do not indicate in info command error output whether credentials
    owned by someone else exist, to avoid giving potentially useful
    information to an attacker
  - delegate credentials with minimum lifetime of 5 minutes to avoid
    problems with clock skew
  - fixed build problem with GT 2.4/3.0 introduced in v3.4:
    EVP_MD_CTX_cleanup() wasn't in OpenSSL 0.9.6

v3.4 19 Dec 2005
  - added myproxy-test -valgrind option for detecting memory errors
  - fixed memory errors found with myproxy-test -valgrind
  - fixed handling of lifetime=0 requests in myproxy-server

v3.3 2 Dec 2005
  - API changes: new trusted_retrievers member for
    struct myproxy_creds and struct myproxy_request_t
  - generate 1024 bit keys instead of 512 bit keys
  - add support for certificate-only authentication to the

    trusted_retrievers options
  - add support for CA username to DN resolution via LDAP using
    myproxy-server.config ca_ldap options
  - add myproxy-server authentication support for Pubcookie
    (http://www.pubcookie.org/) granting cookie via
    pubcookie_granting_cert and pubcookie_app_server_key

  - fixed myproxy-test GT 2.4 compatibility problem in v0.6.5
  - fixed myproxy_get_delegation() signature, erroneously changed in
    v0.6.2, to maintain API-level compatibility
  - added dynamic buffer management for improved handling of large

v0.6.5 8 Apr 2005 (GPT package version 1.17)
  - added support for RFC 3820 proxy certificate format
  - renamed myproxy-get-delegation to myproxy-logon;
    kept myproxy-get-delegation symlink for backward compatibility
  - added myproxy-store and myproxy-retrieve commands for storing and

    note myproxy-retrieve support must be explicitly enabled by
    setting authorized_key_retrievers in myproxy-server.config
  - write temp proxy to /tmp/myproxy-proxy.<uid>.<pid> instead of

  - improve error messages for too-short passphrases (6 character minimum)

v0.6.4 4 Jan 2005 (GPT package version 1.16)
  - fixed file permission bug in myproxy-admin-load-credential

v0.6.3 22 Nov 2004 (GPT package version 1.15)
  - updated GPT packaging for compatibility with GT 3.9.3
    (globus_gssapi_gsi-4.0)
  - added support for $GT_PROXY_MODE="old" in myproxy-get-delegation,
    to retrieve a "legacy globus proxy" from an end-entity certificate
    stored in the MyProxy repository.
  - modified client tools to attempt connecting to the server first,
    before prompting for user input, to catch server problems early.
  - added initial experimental support for Kerberos authentication via
    the SASL/GSSAPI mechanism.
  - removed dependency on perl Expect package in myproxy-test
  - added myproxy-test -startserver option
  - added myproxy-server --pidfile option to ease myproxy-server
    shutdown

v0.6.2 21 Jun 2004 (GPT package version 1.14)
  - added initial experimental support for PAM authentication via
    the SASL/PLAIN mechanism.
  - changed myproxy-admin-change-pass so an empty pass phrase
    can be used for unencrypted keys (for example, for renewal keys)
  - fixed myproxy-admin-adduser to not depend on nonexistent
    myproxy-admin-adduser-config command
  - removed pass phrase functions from myproxy-admin-load-credential,
    so the existing pass phrase on the source key is kept as is.
    Use myproxy-admin-change-pass to change the pass phrase of a
    credential after loading.
  - fixed GT 2.2 and Java CoG incompatibility introduced in v0.6.1.
    Note: if repository contains end-entity credentials, Java CoG
    will retrieve old-style (legacy) proxies because the Java CoG
    certificate request doesn't specify the proxy type.
  - changed signature of myproxy_get_delegation() method.
    original signature is restored in v2.0.

v0.6.1 30 Mar 2004 (GPT package version 1.13)
  Fixed a bug where the myproxy-server would always delegate new-style
  proxy credentials from end-entity credentials in repository.  The
  myproxy-server now respects proxy type in the certificate request
  when end-entity credentials are stored in repository.  However, if
  the repository contains proxy credentials, the server will delegate
  a proxy of the same type as stored in the repository irrespective of
  the certificate request, because new-style and old-style proxies
  can't be mixed.  This bug fix resulted in an incompatibility with GT
  2.2 and Java CoG clients, fixed in v0.6.2.

v0.6.0 22 Mar 2004 (GPT package version 1.12)
  - added max_proxy_lifetime server configuration option for limiting
    the lifetime of retrieved credentials

v0.5.9 28 Jan 2004 (GPT package version 1.11)
  - removed requirement for /dev/urandom and instead let OpenSSL seed
    its random number generator itself using its standard methods
  - added myproxy-admin-change-pass command
  - changed myproxy-get-delegation -d option to have effect even when
    -a option is not given
  - added support for OpenSSL 0.9.7

v0.5.8 23 Sep 2003 (GPT package version 1.10)
  - fixed networking problem with v0.5.7 on some platforms

v0.5.7 25 Aug 2003 (GPT package version 1.9)
  - fixed additional problems with handling large credentials
  - bugfix: myproxy-admin-load-credential fails to prompt for
    passphrase of source credential in versions 0.5.4-0.5.6.

v0.5.6 31 Jul 2003 (GPT package version 1.8)
  - added support for Globus Toolkit 3.0 libraries
  - added support for new GSI proxy certificate format
  - fixed 'myproxy-info -d'
  - fixed credential problem when using Globus Toolkit 2.4 libraries
  - removed buffer length restriction in credential renewal protocol

v0.5.5 30 May 2003 (GPT package version 1.7)
