Red Hat Bugzilla – Bug 11608
High UID values cannot be set
Last modified: 2008-05-01 11:37:55 EDT
If the UID is greater than 65536 the UID for this user defaults to a value
8402. Changing the login.defs file and re-creating the user has no effect.
This is a kernel limitation that will be fixed in the 2.4 series.
