[Bug 996293] Re: Cannot login using active directory users ( Unknown id: $username )

[Justin Jon L. Jereza]

Hello Scott,

The exact idmap config that had the problem is as follows:

idmap config * : backend = tdb # automatically generated by samba
idmap config EXAMPLE : backend = rid
idmap config EXAMPLE : range = 10000 - 20000

There was no "idmap config * : range" configured. No errors were
generated when I ran testparm or in the logs. Later, I tried adding
"idmap config * : range" and that fixed the issue.

Title:
  Cannot login using active directory users ( Unknown id: $username )

Status in “samba” package in Ubuntu:
  Incomplete

Bug description:
  I'm currently having this issue on Ubuntu 12.04. I've verified that
  I've done everything listed in
  https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto. The
  smb.conf configuration I'm using is the same as the one I used in
  10.04 (which works) with the exception that idmap config is used in
  place of idmap backend/uid/gid.

  - wbinfo -u / -g lists all the active directory users / groups just fine.
  - getent passwd / group fails at listing active directory users / groups.
  - wbinfo -a $username authenticates the user properly.
  - wbinfo -i $username fails to display the user info.

  I've attached my nsswitch, pam, and samba configuration as well as
  test.log which contains a log of the commands I've used to try to
  troubleshoot this issue.

  I haven't seen anything unusual in the winbind logs.
