Hi,
I've setup Samba 3.5.6 as a member server in a 2003R2 domain with a
single dc, idmapping is by rfc2307 with a tdb backend for builtin
accounts etc, I can list users and groups using wbinfo and I can
create shares and access them from the windows server, files and
folders owned by ad users show the correct user and group names so
mapping appears to be working, I can su to ad accounts but I am unable
to ssh into the system as a AD user.
Relevant config files:
cat /etc/samba/smb.conf
[global]
debug hires timestamp = yes
workgroup = SAMBATEST
security = ADS
winbind use default domain = true
realm = SAMBATEST.LOCAL

[2010/10/20 12:43:15.749729, 3]
winbindd/winbindd_pam.c:1466(winbindd_dual_pam_auth)

winbindd/winbindd_pam.c:1722(winbindd_dual_pam_auth)
Plain-text authentication for user SAMBATEST\testuser returned
NT_STATUS_NO_SUCH_USER (PAM: 10)
I've tried using ssh -l testuser and ssh -l SAMBATEST+testuser, it
makes no difference to the result or the log entries.
getent passwd/group returns only local users, perhaps a clue as to
what is wrong?
Any suggestions would be appreciated, I've been trying to get this
working for quite a while but I seem to have hit a wall.
Andy
