How to Authenticate users logging into CVS application on UNIX server using Active Directory

Question

Hi,

We have a version control tool (CVS) deployed on UNIX server. This tool maintains its own password file for all users.

I want to use Active Directory to authenticate the users logging into CVS. Any inputs on how it can be achieved?

Also, CVS has different repositories for different projects. I would like to restrict the access of users to some repositories. Is it possible to achieve this using Active Directory?

Any pointers/ sample code will be of great help.

TIA,

S Geek
