PROBLEM: (62574) (PATCH ID: OSF520-1025)
********
When an entry with the maximum possible UID exists in /etc/passwd, a call to
adduser displays, as default uid, the maximum possible uid.
# uname -a
OSF1 wings.xko.dec.com X5.0 538.3 alpha

# grep 65535 /etc/passwd
Test3:SjpcE9Cv4IzyE:65535:15:Tester3:/usr/users/Test3:/bin/sh

# /usr/sbin/adduser

Enter a login name for the new user (for example, john): test4
Enter a UID for (test4) [65535]:
