Hello, I could please use your help regarding issues I am seeing with user access authenticating to my new LDAP server. I am new to LDAP, and am building my first server. I have created a new user (lou) and client (ldapServer) and am trying to authenticate the user through the client. I have configured the LDAP server to also be the LDAP test client. I am seeing the following errors in the /var/log/sssd/sssd_default.log when I run: getent passwd lou or su - lou (Fri Sep 25 16:43:15 2015) [sssd[be[default]]] [fo_resolve_service_send] (0x0100): Trying to resolve service 'LDAP' (Fri Sep 25 16:43:15 2015) [sssd[be[default]]] [sdap_get_rootdse_done] (0x0040): RootDSE could not be retrieved.

I have been doing much reading and am coming up short. My questions are: First: how to delete the current default ACLs using a command line entry, or using a ldapmodify on a .ldif file Second: how to add a new ACL allowing all users access using a command line entry or .ldif file. Once I get the user lou (and other test users) to connect, I will change the ACL access rules for restriction. I need to get it working first. Also, is there a step by step beginners guide for the ACL process? Any help is greatly appreciated. Thank you - Lou
