Hi,

I've got my nss_ldap / pam_ldap to work thru TLS!!

I now have a problem with TLS key usage during login, in this case via ssh.
Despite the error, the login does ultimately succeed.

Output is shown by the logs below. The first is from slapd and the second is
what is shown in the ssh login window. I have debugging enabled in the
ldap.conf file.

Note the line TLS: could not use key file `/etc/ssl/private/serverkey.pem'.

The problem is caused because this key, defined in ldap.conf under
"tls_key", is root readable only.

The problem goes away if I make this key world readable. However, this is
the server's private key and I don't think that it should be world readable.
I think I'm doing something wrong. Hopefully someone can tell me what it is
?

Thanks in anticipation,

John
