I'm trying to implement a custom password scheme through pam and samba. Basically, if a user wants to change their password on a client, the change has to be propagated to the samba server so it can also set the windows password. It works fine to tell users to use 'smbpasswd -r samba.mydomain', or to make passwd an alias that does that, but it would be better to make the change go through PAM so it will work from the GUI as well. Now, I found 2 ways to do this: pam_smbpass and pam_exec, but with both, I seem to be hitting a stone wall. pam_smbpass: On a machine that has a full smb.conf with all the LDAP connections etc (including ldap bind credentials in secrets.tbd), something like password required pam_smbpass.so nullok use_authtok try_first_pass in the appropriate /etc/pam.d files seems to do the trick. However, I don't really want to make every desktop a full member of the domain. So, it would be nice if there was a way to make pam_smbpass connect to a remote samba server, but I haven't been able to find one. Any help in this area would be appreciated. pam_exec: The man page states 'All module types (auth, account, password and session) are provided.' So it should be possible to write a script or prtogram to handle a pam password call, right? But, the script I wrote doesn't seem to receive the old or new password. And re-reading the documentation, I notice that nothing is mentioned about passing a password to the module anywhere, except on authentication, when expose_authtok will do that (then the password will be passed through stdin). But nothing like that when called for a password change. Again, what did I miss? Is the password module type not fully implemented, or should this be handles in another way? (OS: Fedora 15, RHEL 6, both same situation) David Jansen PS: I know a 3rd option would be to switch everything over to winbind, which may or may not work in our complex situation with various Windows domains with trusts. The point is: everything else works, except for a consistent password change method, so before we decide to redesign the whole setup, we want to be absolutely sure that there isn't something simple we are overlooking.
