svn commit: samba r24263 - in branches/SAMBA_4_0: source/dsdb/samdb/ldb_modules testprogs/ejs

[abartlet at samba.org]

Author: abartlet
Date: 2007-08-07 09:01:08 +0000 (Tue, 07 Aug 2007)
New Revision: 24263

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=24263

Log:
Fix bug 4846 (unable to copy users in MMC Active Directory Users and
Computers).

We now generate a security descriptor for each object, when it is
created.  This seems to keep MMC happy.  The next step is to honour
it.
