How to define username?

[aubreybox]

Hello I want to try to use that module for authenticating with pam and sasl.
Is it possible to affect the username so that I can bind a (maybe different) username to a public key?
Is there any documentation on how to adapt this module?

Basically the idea is that bob@client connects password less to alice@server without actively mentioning he's alice - that information would be stored serverside (e.g. username:key-database)

I think this may be provided by another pam module called pam_alias. Note that the order in the pam stack would matter a great deal since this module uses PAM_USER and PAM_RUSER.

Also, I'm incredibly intrigued about your use case. If you get this working, would you mind giving more details on how you're using this with sasl?

Thanks!
