Feature suggestion - strip prefix and/or suffix on supplied username

[Giddings, Bret]

Hi all,

I can't find anything online that matches this so it doesn't look like pam already has this feature.

At my site, many users will either use NETBIOSDOMAIN\username or username at dns-domain when trying to authenticate. Depending on luck, either might work on things windows related. However, when we slip into the linux realm, both will fail. So, I was wondering if there were a module which would sanitise the supplied username and strip (specified) prefixes or suffixes if present. That would then result in far fewer support calls to the helpdesk when they were in fact presenting perfectly valid credentials, albeit with known but redundant prefixes or suffixes.

Is this possible at all?

Regards,

Bret Giddings
