Hello, I have a problem with acl and group. I configured a proxy slapd and add acl (see slapd.conf below)
Read the slapd-ldap(5) manpage. Since your remote server is AD you must configure explicit Bind credentials for any access of the remote server. In this case, back-ldap cannot look up the remote group memberships because you have failed to configure acl-bind.
Run slapd with -d7 and it will be obvious that this is the problem.
When I run a ldapsearch command with user 'Test User' the attributes are displayed. It's Ok
But when I run the same ldapsearch command with user 'Synchro1 User' the message 'Insufficient access (50)' are displayed. It's not ok The user 'Synchro1 User' is member of CN=Grp_Users_UG,OU=Gina,OU=Applications,DC=activedir,DC=example,DC=ch
Are you an idea ? Thank you for you help Dysan
