Description Stefan 2009-03-10 11:37:07 UTC

i don't know if its a bug, but i wanna post this output of my log.smbd. This happens when I startup the samba. It should connect to my openLdap but it didn't. The OpenLdap Server works fine, I can add/modifiy users, groups etc. 

This is supposed to be an PDC, in the near future i wanna add a BDC. Thats why I need the LDAP support. But i always get stuck on this error.

I hope you can help me. In addition I post my smb.conf ... If you need to know anything more, let me know :-)

Comment 1 Volker Lendecke 2009-03-11 02:10:20 UTC
It is highly likely that this is a configuration problem with your LDAP and not really a bug in Samba, that's why I'm closing this as invalid.

I would guess that your Samba daemon is just not able to write to your LDAP DIT, possibly due to access controls or another mis-configuration of either Samba or LDAP.

Please post your smb.conf and a network trace between smbd and your LDAP server to the Samba users' mailing list samba@samba.org. Information on how to create useful network traces can be found under
