samba3-3.4.11-42.el5
However I have moved to using idmap_rid, as I will have cold standbys of
machines that I want to be able to access SAN data, with the same IDs.
So how does one go about clearing the samba user cache? I had it set up with users starting
at 10000. With RID I have now brought this down to 500 (so I can easily see the difference).
I deleted the winbindd_* files& folder in /var/lib/samba, but when I use a "getent
passwd brian.omahony" its showing the id as 100000
Thanks

What version of samba? I found that samba 3.0.x (as bundled with
solaris) had problems with idmap. This was with LDAP backend, a Samba DC with
trusts to Windows 2003 domain (in NT domain compatibility
mode.) Samba would allocate idmap entries in ldap, and would populate the TDB
cache files. but when the cache timeout expired, the cache files were not
repopulated.
Long and short- I don't think Samba 3.0.x plays nice with Windows
2003. It doesn't work with Windows 2008 domains (2003 mode.)

Subject: [Samba] Samba Authentication wrecking my head [ADS]
Ive recently installed three servers with RHEL5u5. After some messing on the
original, I got samba working with ADS authentication. I then went and got it
working so that users could log in using their domain name& password to the
box. I got this working with both no restriction, and ADS group restriction. I have
left it on no restriction wheil I get these systems up and running.
I then copied my configuration files (krb5.conf, samba.conf, system-auth.conf)
to the second machine. Everything works. Rebooted, everything is fine. System
running as expected.
I copied to the third machine. Everything worked fine. I was able to log in
using two users (mine and a colleagues). Set up some other machine stuff,
rebooted, and passed the machine over.
I was then informed (naturally 5mins after I left the office) that there was something
wrong. Those two accounts worked from both a samba perspective, and a login perspective.
However a third account that was supposed to work, failed with "su: user ccadm does
not exist". Now samba doesn't work for any user other than the original too, and the
same goes for logins.
I tried net ads leave, kdestory, renaming the system, rebooting. I have
rejoined the domain as both that system name, and a new one, with no issues:
[root@akbarTRAP log]# wbinfo -t
checking the trust secret via RPC calls succeeded [root@akbarTRAP
log]# net ads testjoin Join is OK [root@akbarTRAP log]# wbinfo -u |
grep ccadm Ccadm
So my questions are:
1. Where the hell are these accounts being cached, that work.
2. What the hell has happened to make this no longer work.
3. Why if I can see all the users& groups can I not log in, or get
samba working.
This is really starting to get on my nerves. I just cannot understand why if it
can see the users using wbinfo, why it is telling me they don't exist.
Would really appreciate some help on this.
