[Samba] samba-3.5.2 - "getent group" not returning any info

[robert.gehr]

Hello there

I just installed 3.5.2 and encountered the following. Compile worked all
right but "getent group" would not give back any results, though "getent
passwd" did list those AD users. The server runs as AD member and
winbind seems to work normally. "wbinfo -u" and "wbinfo -g" return the
desired info just "getent group" sucks. 

It works using the previous 3.3.8 version as well as with 3.4.7 using an
unchanged smb.conf.

I can live with 3.4.7 but thought it might be of interest.

Thanks for all the efforts.

Rob

------------

Here the relevant smb.conf:

winbind trusted domains only = No
winbind use default domain = Yes
winbind nested groups = Yes
winbind separator = /
winbind enum users = yes
winbind enum groups = yes
winbind expand groups = 3
idmap uid = 10000-20000
idmap gid = 10000-20000

----------------
and strace for "getent group"
