PAM authentication and PPolicy issues

Hi Everybody,

I'm have some RHEL6 machines that use an LDAP server to authenticate. I need to introduce in the server some checks on passwords using PPolicy. PPolicy works fine, the problem is that to use pwdCheckQuality and pwdInHistory I need to save passwords in clear text in the LDAP server. I did a search to find out if there is a way to let PAM to use clear text password to authenticate but it seems that it sends SHA hashes, so authentication fails. Do you have any suggestion?

Thanks, Francesco
