Now, am I right in thinking that I can use "clear" as long as I'm using
SSL to the LDAP server?
Yes, sending un-hashed passwords over SSL is very safe.
What about setting local non-LDAP passwords with this set to "clear"
isn't that dangerous?
No worries about this, pam_ldap password settings don't affect passwords
stored locally in /etc/passwd. Your /etc/pam.d/system-auth password stack
for Linux LDAP clients probably looks something like the below:
password requisite /lib/security/$ISA/pam_cracklib.so retry=3 type=
password sufficient /lib/security/$ISA/pam_unix.so nullok use_authtok
md5 shadow
password sufficient /lib/security/$ISA/pam_ldap.so use_authtok
password required /lib/security/$ISA/pam_deny.so
When setting local passwords, the stack will never even invoke pam_ldap,
since the pam_unix line is "sufficient".

Subject: Re: password policy on FDS 1.0.2 - doesn't
seem to work?
I think have have an idea about this now ... the problem seems to be the
exop password modify request. Subtree and user policies are ignored from
ldappasswd (which uses exop)
PAM (when pam_password is set to "exop" in /etc/ldap.conf)
But are ok from
Ldapmodify
PAM (when pam_password is set to "clear" in /etc/ldap.conf)
So, the RFC 3062 password modification requests seem to bypass the
subtree and user policies. I see this behaviour in 1.0.2 and 1.0.4.
Now, am I right in thinking that I can use "clear" as long as I'm using
SSL to the LDAP server? What about setting local non-LDAP passwords with
this set to "clear" isn't that dangerous? I can't use "ssha" for
pam_password as then password changes don't seem to work at all, which
is why I changed to "exop".
