Re: NFS UID GID sync up

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Hello Nate,

NIS is really a means of synchronizing files across a network.  Since 
many Unix systems use the same file in the same format for storing 
userids and passwords, you can synchronize the password database this 
way, which is a useful feature.

However, your 170 is running i5/OS, which is not Unix.  It doesn't use a 
file for userid/password management, and even if it did, the odds aren't 
good that it would match the Unix format.  So NIS is definitely not a 
choice.

What you might try doing is creating a file with the following Unix 
shell command:

awk -F: '{print $1 "," $3 "," $4}' < /etc/passwd > /tmp/myfile.csv

This will give you a CSV file containing the user name, UID and GID, 
separated by commas.  You should then be able to transfer it to i and 
use the CPYFRMIMPF command to convert it to a database file.

Once in database format, have a CL program that reads your database file 
and for each record in the file, do:

CHGUSRPRF USRPRF(&USRPRF) UID(&UID) GID(&GID)

Granted, this won't run automatically when a profile changes, you'll 
have to re-run the process to re-synchronize.   But, still...  it's a 
lot better than changing each user profile by hand.
