Hi guys
We recently upgraded our Samba clusters from 4.7.5 to 4.8.3 and noticed
a difference in behavior for winbind.
The situation is as follows
Assume we have a local Linux user XYZ (UID 519) as well as a AD user
object XYZ (UID 30001).
idmap config * : backend = tdb2
idmap config * : range = 30000-50000
In our share definitions we regularly use the "force user" directive.
In 4.8.3, when using "force user = XYZ", we are forcing the UID of the
AD user object XYZ (UID 30001) and not the local Linux user XYZ (UID 519).
In 4.7.5 this worked fine.
Is this change intentional or a defect?
Moreover, when running "id XYZ", the correct UID 519 is given.
The groups, however, are a mix of local groups and AD groups. This
behavior was also different in 4.7.5.
4.8.3
# id XYZ
uid=519(XYZ) gid=1(bin) groups=1(bin),30004(DOSIM000+domain users)
# id xyz
uid=30001(DOMAIN+XYZ) gid=30004(DOSIM000+domain users)
4.7.5
# id XYZ
uid=519(XYZ) gid=1(bin) groups=1(bin)
# id xyz
id: ‘xyz’: no such user
Thanks for your help
