Hi all, For all the LDAP gurus out there, I have openldap setup on FC2 to be a client of MS server 2003 AD, user authentication works fine, but attempts to change passwd failed. [root@mymachine root]# passwd yxiao Changing password for user yxiao. Enter login(LDAP) password: New UNIX password: Retype new UNIX password: LDAP password information update failed: Unknown error 00002077: SvcErr: DSID-03190DC8, problem 5003 (WILL_NOT_PERFORM), data 0 passwd: Permission denied and in /var/log/messages Sep 28 19:46:59 mymachine passwd[8537]: pam_ldap: ldap_modify_s Server is unwilling to perform Sep 28 19:47:10 mymachine passwd[8538]: pam_ldap: ldap_modify_s Server is unwilling to perform Many thanks, Yang
