Is someone of you using Samba on AS400 and how do you handle this problem.

I'm not using Samba within IBM i but in Linux. And there is exactly the same problem: You have to support two user/password "databases". This stems from the different ways of encrypting/hashing the user password which gets saved to disk, so no plaintext passwords are saved.

Years ago, this could be somewhat mitigated by telling Samba to allow unencrypted passwords, so it could utilize /etc/shadow directly. I'm not sure if current Windows versions could be told to handle plaintext passwords. I also don't recommend using plaintext passwords today.

I thought that when nothing other is possible i would register with QIBM_QSY_VLD_PASSWRD and send new Passwords to a Job via DataQueue which calls pdbedit to change the users in the samba-db. But this is not a nice solution.

I guess you've no other choice. In fact, I think this is a nice way to sync passwords. If anyone will change his password through Windows facilities (RPC?), they'll stay different, though.

Maybe it's possible to configure Samba to disallow password changes from the Windows side?

:wq! PoC
