Yes, but, pam_unix handles password changing with /etc/passwd, NIS,
NIS+ (?) and so on and pam_ldap handles password changing with LDAP and
so on.

I.e., there are two ways in which pam_crypt has to be modular:

1. Crypt() types

2. Name service types -- use NSS [getpwnam()] :)

3. Password changing protocols -- related to (2), but NSS doesn't help :(

The interesting thing is that (1) is NOT related to either (2) nor (3).

That is, you can use multiple different crypt types within a single name
service (though you can have only one crypted password per-user). So
modularity with respect to (2) and (3) must not be related (1).

So, is pam_crypt modular with respect to password changing?

Are you providing any password changing modules? Which ones?

It's also on the Kerberos lists. Very obnoxious.
