If I understood the requirement correctly, every time a user joins or leaves a list, you want LISTSERV to immediately connect to an LDAP server and update certain data in certain tables in a format that, I imagine, is only in use at Temple? :-) Well, I think it can be done, but not by adding "TEMPLE_PORTAL=1" to your configuration and restarting ;-) You would have to set up a list exit for every list and have that exit do the LDAP work.
