First of all, i have nss_ldap-1222-1.6, pam-0.72-26, openldap-1.2.11-15, Linux RH 7. I, im having a problem authenticating IMAP users through ldap. But the problem is just relaed to IMAP authentication, not other kinds (ssh -> good , console ->good). Does any one has any solution? I have also made a copy of the /usr/doc/nss_xx-xx/pam.d/imap to /etc/pam.d/imap, but no luck. I have also read the docs at: http://www.openldap.org Can any one plase tell me what is happening? Thanks in advance.
