Importing existing passwd and group file to aix 3.1

[Lyle Meier]

 We have aquired an rs6000. We would like to be able to copy our existing
 password file over to the system and have it work. (We distribute a 
 master password file to our yp domains, and the RS-6000 should set
 in a different domain than everyone else). When one copies the password
 file over one can log in as a user but an error message is created about
 being unable to set terminal permission and the user is logged off.
 Trying via telent yields similar results and a message that the 
 connection was closed. 

 A second related question. We have a central administration for uid's.
 If one creates a user using SMIT how can one set the uid for the user
 short of going thru the change user mechanism?

 Thank you for your help.
