samba - Jan 2005 - Problem resolving groups in 3.0.10

Hi,

we are running a Solaris 8 server on which we installed Samba 3.0.10. We 
configured it with:

    --prefix=/usr/local/samba
    --with-pam
    --with-acl-support
    --with-winbind

If Samba is started and I use wbinfo -u I can see a list of all our user. If I 
use wbinfo -g I can see a list of all our groups. But listing all the file in a 
share, when logged in via ssh, not all of our groups are resolved. For some 
groups I can see their names and for other groups I can see their GID. Now I 
take one of this GIDs and try to query their name doing

    wbinfo --gid-to-sid=<GID>  -->  here I get <SID>
    wbinfo --sid-to-name=<SID> -->  here I get Name of the group

everything is fine. Are there any hints, why this is happenig?


TIA

    Sven
