Take maintainership.
New in 2.1.25
-------------
* Make sure that a failed authorization doesn't preclude
further server-side SASL authentication attempts from working.
* Fixed a crash caused by aborted SASL authentication
and initiation of another one using the same SASL context.
* (Windows) Fixed the random number generator to actually produce random
output on each run.
* Be protective against calling sasl_server_step once authentication
has failed (multiple SASL plugins)
* Fixed several bugs in the mech_avail callback handling
in the server side code.
* Added support for channel bindings
* Added support for ordering SASL mechanisms by strength (on the client side),
or using the "client_mech_list" option.
* server_idle needs to obey server's SASL mechanism list from the server
context.
* Better server plugin API mismatch reporting
* Build:
- Updated config to the latest GNU snapshot
- Fixed SASL's libtool MacOS/X 64-bit file magic
* New SASL plugin: SCRAM
* New SASL plugin: GS2
* DIGEST-MD5 plugin:
- Allow DIGEST-MD5 plugin to be used for client-side and
server-side HTTP Digest, including running over non-persistent
connections (RFC 2617)
- Use the same username for reauthentication cache lookup and update
- Minimize the number of auxprop lookups in the server side DIGEST-MD5
plugin for the most common case when authentication and authorization
identities are the same.
- Updated digestmd5_server_mech_step2() to be more defensive against
empty client input.
- Fixed some memory leaks on failed plugin initialization.
Prevent potential race condition when freeding plugin state.
Set the freed reauthentication cache mutex to NULL, to make errors
due to mutex access after free more obvious.
- Test against broken UTF-8 based hashes if calculation using special
ISO-8859-1 code fails.
- Fixed an interop problem with some LDAP clients ignoring server
advertised realm and providing their own.
* GSSAPI plugin:
- Fix to build GSSAPI with Heimdal
- Properly set serveroutlen to 0 in one place.
Don't send empty challenge once server context establishment is done,
as this is in violation of the RFC 2222 and its successor.
- Don't send maxbuf, if no security layer can be established.
Added additional checks for buffer lengths.
* LDAPDB plugin:
- build fixes
New in 2.1.24
-------------
* Order advertised server-side SASL mechanisms per the specified 'mech_list'
option or by relative "strength"
* Make sure that sasl_set_alloc() has no effect once sasl_client_init()
or sasl_server_init() is called
* Fixed sasl_set_mutex() to disallow changing mutex management functions
once sasl_server_init()/sasl_client_init() is called (bug # 3083)
* Removed unused mutexes in lib/client.c and lib/server.c (bug # 3141)
* Added direct support for hashed password to auxprop API
* Don't treat a constraint violation as an error to store an auxprop property
* Extended libsasl (auxprop) to support user deletion
* Extended SASL auxprop_lookup to return error code
* Updated sasl_user_exists() so that it can handle passwordless accounts (e.g. disabled)
* (Windows) Free handles of shared libraries on Windows that were loaded
but are not SASL plugins (bug # 2089)
* Prevent freeing of common state on a subsequent call to _sasl_common_init.
Make sure that the last global callback always wins.
* Implemented sasl_client_done()/sasl_server_done()
* Added automatic hostname canonicalization inside libsasl
* Made sasl_config_init() public
* Strip trailing spaces from server config file option values (bug # 3139, bug # 3041)
* Fixed potential buffer overflow in saslautd_verify_password().
* Fixed segfault in dlclose() on HPUX
* Various bugfixes for 64bit platforms
* Fixed bug # 2895 (passing LF to sasl_decode64) in sample/sample-client.c,
sample/sample-server.c, utils/smtptest.c
* pluginviewer: Code cleanup, improved human readable messages
* Build:
- (Windows) Updated makefiles to build with VC 8.0 (VC++ 2005)
- (Windows) Added Windows64 build
- Updated to use .plugin extension on MacOS
- Changed 64bit HP-UX build to use .so for shared libraries
* saslauthd:
- Fixed bug counting double-quotes in username/password in
auth_rimap.c. Also fixed bug zeroing password.
- auth_krb.c: improved diagnostic in the k5support_verify_tgt() function.
- auth_sasldb.c: pid_file_lock is created with a mask of 644 instead of 0644
- auth_shadow.c: Define _XOPEN_SOURCE before including unistd.h,
so that crypt is correctly defined
- auth_getpwent.c: Fixed Solaris build
* SASLDB plugin:
- Fixed spurious 'user not found' errors caused by an attempt
to delete a non-existent property
- Added direct support for hashed password to auxprop API
- Sleepycat driver: Return SASL_NOUSER instead of SASL_FAIL when the database
file doesn't exist
- Ignore properties starting with '*' in the auxprop store function
* SQL plugin:
- Added support for SQLITE3
- Uninitialized variables can cause crash when the searched user is not found
- Added direct support for hashed password
- Ignore properties starting with '*' in the auxprop store function
* LDAPDB plugin:
- Added code to extend LDAPDB into a canon_user plugin in addition
to its existing auxprop plugin functionality
* PLAIN plugin:
- Advertise SASL_SEC_PASS_CREDENTIALS feature
* LOGIN plugin:
- Advertise SASL_SEC_PASS_CREDENTIALS feature
* DIGEST-MD5 plugin:
- Fixed a memory leak in the DIGEST-MD5 security layer
- Fixed memory leaks in client-side reauth and other places
- More detailed error reporting.
- Fixed parsing of challenges/responses with extra commas.
- Allow for multiple qop options from the server and require
a single qop option from the client.
* GSSAPI plugin:
- Check that params->serverFQDN is not NULL before using strlen on it
- Make auxprop lookup calls optional
* EXTERNAL plugin:
- Make auxprop lookup calls optional
* NTLM plugin:
- allow a comma separated list of servernames in 'ntlm_server' option

SASL is a method for adding authentication support to connection-based
|
|
protocols. To use SASL, a protocol includes a command for identifying and
|
|
authenticating a user to a server and for optionally negotiating protection
|
|
of subsequent protocol interactions. If its use is negotiated, a security
|
|
layer is inserted between the protocol and the connection.
|
|
|
|
This is the Cyrus SASL plugin that implements the SCRAM authentication
|
|
mechanism.
