- Log -----------------------------------------------------------------
commit 3ed2c65bde0c2e5ad10cf777dae8a2d3e626a42c
Author: James Peach <jpeach at samba.org>
Date: Mon Apr 7 15:28:10 2008 -0700
Remove unused variable.
commit 59a2bcf30fef14ecc826271862b645dd3a61cb48
Author: Bill Ricker <bricker at apple.com>
Date: Mon Apr 7 15:02:56 2008 -0700
Fix Kerberos interop with Mac OS X 10.5 clients.
Ignore optional req_flags. Use the Kerberos mechanism OID negotiated
with the client rather than hardcoding OID_KERBEROS5_OLD.
commit fd168e7b5065ba15b1cf56522b6810b8e6fdd7d5
Author: James Peach <jpeach at samba.org>
Date: Mon Apr 7 15:00:41 2008 -0700
Use bool for BOOL and true/false for True/False. We need lowercase
bool to get the declarations picked up by the prototype parser.
