winbindd nsswitch fails with RID backend on 12.04

[Torsten Krah]

After upgrading to 12.04 i can't login anymore with my users:

wbinfo -i $USER

does only return:

failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for user $USER

where wbinfo -u oder wbinfo -g works.

Upstream report here:

Thanks for reporting this bug. Marking confirmed due to upstream report. Marking high priority as there appears to be no workaround and it affects core functionality (login).

I am having the same problem: wbinfo -i $USER gives
failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for user $USER

using Samba 4.0.7 (compiled by sernet, https://download.sernet.de/packages/samba/4.0/ username and password needed) solved partly the problem.
