Changing password for various users with same UID

kapil.kshirsagar · 07-04-2008, 03:25 AM

Hi All,

I have build an NIS server on RHEL 5, this database contains some users with same UID, now when i try to change password for xyz user i get prompt to change password for the another associated user.

For Example : If I have test1 & test2 with same uid 500

when i give yppasswdd test1
this will show me
changing passwd for test2

Is there any way to resolve this.

Thanks,
Kaps

UIDs must be consistent across all systems. Your configuration is currently broken. You need to make the same username have the same UID everywhere. That is the entire point of NIS. One master.

Without this consistency, over NFS, user joe=500 will have access right to the files and directories of user sally=500 on another system.

I want that my all users with same UID can span across the files, as for testing purpose each user has another username attached with same uid. I am facing while changing the problem which I have mentioned above.

Yes, you are faced with changing all the overlapping username/uids. Get a list of all of them, see which UIDs have two or more user names mapping to a single UID, and create new UIDs for all but one of those users.
