samba - Jul 2006 - 3.0.22 to 3.0.23a and sambaSID

Hi, 

I try to upgrade 3.0.22 to 3.0.23a and have read the RELEASE NOTES, but I
cannot connect via windows after upgrading.

So I copied the new samba.schema and added "index sambaSID sub" to
slapd.conf. 

I stopped the ldap Server and ran slapindex.

So after doing an smbldap-usershow on console I saw all informations about
the wanted user, but I am not able to logon via windows.

What did I miss?

Greetings

Sascha
