Im still not 100% on this.  So you're saying one has more than the 
regular master.passwd on the server?  I thought it used the primary's 
regular passwd and master.passwd - in which case you would think you 
would update it there, and the rest would see it.

Im confused out.

I hear that one!

The question is due to being gun shy - under SCO if you maintain a shadow 
file, and you have more than 30 or so users, and a user changes their 
password, no one can log in anyplace for up to 10 minutes while the boxes 
sync themselves - any more than 50 users and you end up with chewed and 
corrupted /etc/passwd and /etc/shadow.  The worse grinding is on the master.

Can you tell I really love SCO?  Well I dont!  But I dont want to port 
everything only to find a worse mess...

Im really confused on the master.passwd issue - because then how does one 
make a new account? the same old adduser? or do you have to manually add 
something to this mystery file..

I feel dumb today...
