From bf75a22ffc04dfa0387a1389750b0a1e6d3ac397 Mon Sep 17 00:00:00 2001
From: Ralf Haferkamp <rhafer@suse.de>

Subject: [PATCH] Added option to use libcrypto instead of NSS.
crypto_sha512crypt.c is a clone of nss_sha512crypt.c with the exception that
all usage of NSS and related libraries has been switched to libcrypto.
I renamed nss_sha512crypt.h to sha512crypt.h since it is common to both
crypto_sha512crypt.c and nss_sha512crypt.c. Note that the random number
generator is not seeded manually and thus relies on seeding done
automatically by libcrypto. On some systems without /dev/urandom
seeding may not be performed.
See http://www.openssl.org/docs/crypto/RAND_add.html.

Fri Sep 3 13:17:48 UTC 2010 - rhafer@novell.com
- No dependencies on %{release}
-------------------------------------------------------------------
Mon Aug 30 12:57:47 UTC 2010 - rhafer@novell.com
- Updated to 1.3.1
* Fixes to the HBAC backend for obsolete or removed HBAC entries
* Improvements to log messages around TLS and GSSAPI for LDAP
* Support for building in environments using --as-needed LDFLAGS
* Vast performance improvement for initgroups on RFC2307 LDAP servers
* Long-running SSSD clients (e.g. GDM) will now reconnect properly to the
daemon if SSSD is restarted
* Rewrote the internal LDB cache API. As a synchronous API it is now faster
to access and easier to work with
* Eugene Indenbom contributed a sizeable amount of code to the LDAP provider
- We now handle failover situations much more reliably than we did
previously
- We also will now monitor the GSSAPI kerberos ticket and automatically
renew it when appropriate, instead of waiting for a connection to fail
* Support for netlink now allows us to more quickly detect situations
where we may have come online
* New option "dns_discovery_domain" allows better configuration for
using SRV records for failover
- New subpackages: libpath_utils1, libpath_utils-devel, libref_array1
and libref_array-devel
