Hello,

I have some server configured soas to allow both insecure POP/IMAP and POP/IMAP over SSL. We are using UW IMAP and PAM for authentication.

What I would like to do is force *selected* users to only be allowed to login via the SSL ports. I know I can do this by putting these people on a different server and either blocking the insecure ports or compiling imap/pop to only allow SSL; however, this is not an option.... they have to stay on the same server as other users who do want to use insecure logins.

So,

* Is there some way to use different PAM files for SSL and non-SSL connections? If so, we could use PAM-Listfile to allow or deny access on a per-user basis.

* Are there other suggestions that are clean?

I suppose a "dirty" solution would be to hack the authentication part of imapd to do a pam-listfile similar thing ... knowing if the login is using SSL or not. However, I prefer to keep my IMAPd code as close as possible to the source distribution.

Any suggestions are very welcome.

Thank you,

-Erik Kangas
