Description jay_lyerly 1999-08-19 00:15:03 UTC

User id's with values greater than 65536 ( or is it 65535? )
don't work.  For instance, I can create a user with uid
100,000.  That user can't log in.  Watching syslog during
the login shows a session open for the user, then
immediately close.  'su' spits at the username with a
invalid arguement error and refuses to set the userid to
100,000.

This has become an issue at NCSU where the eos/unity system
now has ~70,000 users.

The kernel's UID type is only 16 bits. Sorry. When this
is fixed in the kernel, it will work elsewhere.

You might try experimental 32-bit uid support, available at:
