It may be wise to set pwdCheckQuality=2 in the password policy to make
sure that passwords are only accepted in clear text.

It would also be wise to write LDAP ACLs such that password changes
are not accepted unless the session is encrypted.

Thanks to both of you for the responses. Changing pam_password from md5 (which was inserted by Redhat's authconfig) to exop fixed the password policy issues. Also, setting pwdCheckQuality=2 was helpful in troubleshooting.

I still see in the debug output that the old password is being sent in cleartext when I change it. To be sure I understand correctly, Buchan: this is normal and necessary for ppolicy to check against the history?

Andrew, do you know of a handy example of an acl that enforces encryption on passwd changes?

Thanks again.
