Re: NFS UID GID sync up

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.

Our lab Linux NFS server uses NIS users/groups. When I mount
my home directory from NFS to the as400, the UID & GID
of my 400 user vs the NFS/NIS user don't match and I get permission
denied.

What's the best way to sync these up?
Can OS/400 talk NIS?
How do I edit my user to change the Uid/Gid to match the Ids coming from
NFS?

Thanks
