On HP 10.20, as user root, i do :
# su - kroot
su : Your own ID is unknown

Hi,

What do you see when you execute the following command?

# id

Hope this helps. Regards.

Do 'whoami' and 'who am i' show different userids?

Hi,

It seems that your /etc/passwd file is corrupt. Run 'pwck' to see what's wrong.

Sorry for the inconvenience.

My user root is OK (id, whoami,...)
but the problem seems to be like :
it is a trusted system and somebody added manually a line in the file /etc/passwd.
When restoring the old passwd file, my su command runs well.
