[Samba] 3.0.23 PDC with ldapsam:trusted backend - failed to setup guest info.
Hi everybody. This is my first post here - Im hoping that someone out there can shed some light on my little problem, it's starting to drive me nuts! :) Ive had a look through the archives as well as other methods for finding a solution to my problem but to no avail, so I decided to post here - hope you dont mind! Im migrating an old samba 2.2 PDC to a new system running 3.0.23, we have a requirement not to have local users on this new machine - no problems says I , this will give me a chance to try out an ldapsam backend with ldapsam:trusted. I have populated the nobody and root user accounts (as well as some test users) into LDAP but when I try to start samba, it fails with a "ERROR: failed to setup guest info." error in log.smbd. From what I have seen from a debug level 3 log (attached) of this sequence, it binds to the LDAP directory, finds the root user, hits a permission error (WERR_ACCESS_DENIED) along the way, starts to find my nobody user (I see references to nobody's uid - 60001 - in the log) and then bombs out. nmdb starts up but smbd doesnt come up (for more than a second anyway, if at all) Our directory already has the samba schemas installed and this directory serves PDC requests for another of our domains (that has local unix users defined) - so I am assuming that this is not a schema issue. I am thinking that I have missed something rather obvious along the way, as it is my first time attempting this, or i have done something completely wrong fundamentally and digging myself a deeper and deeper hole as I continue?! Any help would be GREATLY appreciated :) I have included copies of my log.smbd (debug level 3) , my smb.conf and a dump of my root,nobody and nobody group ldap entries. If you need any more information - just ask. Thanks Simon (log.smbd) [2006/08/22 11:44:58, 0] smbd/server.c:main(847) smbd version 3.0.23 started.
