Hi all,

I hope you are all doing ok.

I'm working on a service based on SSH connections and SFTP file transfer.
To make the name and/or id translation work I'm looking for a way the
user and group databases are shared between server and client. If so,
it is very easy.
If not I have to create a mapping.

I can write an utility which
scans every line in /etc/nsswitch.conf and test for words like ldap in
the line starting with passwd: and group: (and also for sss).
If found test it's working and also active on the server.
Maybe you see, this is a lot of work, and testing of all kinds of possibilities.
Is there a simpler way to do that? To get an unique id per user/group
database or something like that.

Thanks in advance,

S.J. Bon
