pam authentication -extension

[Anna C. Squicciarini]

Hi, 

We are  working for a project and trying to see if there is any possible way
to extend PAM authentication 
modules. 
I'd like to change the way authentication is executed and being able to
invoke PAM authentication as required. I thought about using temporary
configuration files, that can specify the particular type of module to be
used.
Do you know if anything in this direction has been done, or if it's possible
to be done?


Thank you
Anna and Abhilasha
