Spotted on Hawaii, a 6.0R uvaxII.
Yes, I know that login servers are not the usual supported tour of duty...

compare the two routines...
remove_pwent and insert_pwent...
remove_pwent opens /etc/ptmp to lock the password file while
insert_pwent only checks for its existance... therefore two
simultaneous additions will lose, right?
Cheers,
