Here could be a problem. I could not change our win 2k3 schema. They were
afraid it could break something... tsss. So i had to use the idmap_rid
module. Which does a good job actually. It uses the last portion of the AD
users SID and adds it to a base set in smb.conf. I issued your commands:
bash-2.03# getent passwd | grep oweinmann
oweinmann2:*:15042:1613:Oliver Weinmann2:/home/oweinmann2:/bin/sh
oweinmann:*:11611:1613:Oliver Weinmann:/home/oweinmann:/bin/sh
oweinmann1:*:15041:1613:Oliver Weinmann1:/home/oweinmann1:/bin/sh
bash-2.03# id -a oweinmann
uid=11611(oweinmann) gid=1613(domain users) groups=10(staff)
bash-2.03# su oweinmann
$ id
uid=11611(oweinmann) gid=1613(domain users)
$ id -a
the "id -a" as user "oweinmann" seems to get stuck. It just sits there. I
noticed when issuing "groups oweinmann" as root it also gets stuck. On some
users the "groups" command seems to be working on some other don't.
