When I use the authconfig script to set up my system for LDAP it does not seem to work. If I su - user it returns the message Incorrect Password. I have altered the /etc/pam.d/system-auth file to read : account [default=bad success=ok user_unknown=ignore service_err=ignore \ system_err=ignore authinfo_unavail=ignore]\ /lib/security/$ISA/pam_ldap.so >From : account [default=bad success=ok user_unknown=ignore] \ /lib/security/$ISA/pam_ldap.so And all works fine now, I found this from an old Redhat 8 bug, I would have thought this would have been fixed by now. Is this change correct, or should I have done something else to make it work other than change the pam config? Thanks, Neil. -- Neil Marjoram.
