We already have that.

Not going to happen, since we don't have LDAP in base.

Requires a PKCS11 implementation in base.  I never finished the one I
started on...

What does this do that pam_group doesn't?

> security/pam_smb          NetBIOS domain logon PAM module

Apparently requires Perl to run, although this may be a bug in the port

> security/pam_ssh_agent_auth PAM module which permits authentication via s=
sh-agent
> sysutils/pam_mount        A PAM that can mount volumes for a user session

That leaves us with the following candidates:

 - pam_jail
 - pam_mkhomedir
 - pam_mount
 - pam_pwdfile
 - pam_ssh_agent_auth

and possibly also

 - pam_require
 - pam_smb

Note that pam_mkhomedir and pam_mount can be implemented using pam_exec
(possibly with some improvements) and scripts.
