I have seen his type of setup before when companies have two different LDAP servers.
One LDAP Server for Employees
One LDAP Server for Non-Employees and System Accounts
The way to make this work, is to pick one of the groups of people and create a Postgres group and add all those users
tothat group. Let's call the Postgres group ldap1_group.
You now need to duplicate each line in your pg_hba.conf file. The first line you will point to ldap1 and the second
lineyou will point to ldap2. Then in the first line update the user field where you might normally have "all" to
"+ldap1_group".The + tells Postgres that this is a group and to use this authentication method for everybody in that
Postgresgroup.
Hope this helps,
Lloyd Albin
