I have two users and they have used the same linux UID.

In iManager tom was created with ID 1090, some where a year later someone has used the same UID 1090 for a new user "machine1".

Now I see that tom his files are all created as "machine1". And actually they are created as tom.

drwxrwxrwx 1 machine1 root 4.0K Jan 20 2012 Upgrade to Office

id tom -> displays machine1 instead of tom
uid=1090(machine1) gid=2000(linuxadm) groups=3000(machineusers)

id machine1 -> crashes when doing id
*** glibc detected *** id: double free or corruption (fasttop): 0x0000000000610a
uid=1090(machine1) gid=3000(machineusers)Aborted

When I do it for user which has no double UID, it displays normal:
uid=1093(bart) gid=2000(linuxadm) groups=2000(linuxadm)

The group linuxadm is added to the server unix object. Also machineusers is added to the unix object.

What do I have to do now?
