[comp.unix.xenix.sco] ct for SCO Unix

mcitron@phad.hsc.usc.edu (Mark Citron) (11/30/90)

Does anyone have a working version of SCO's "ct" command???
My SCO system came with a ct that actually does the callback 
but then does not allow you to login. 

Thanks for any help,

The problem is that when you exec ct from a session it runs with your
'login uid'.  Ct-getty-login all inherit it.  When login tries to
set luid after you enter your login name it finds luid already set.
This causes the 'Bad login user id' message. Maintaining luid separate
from uid is a SCO security enhancement. 

Ct itself is not the cause.  If ct were run from init (which runs without
a login uid) it probably would work fine.
