We configured our Luminis 5.1 system to authenticate users against external LDAP server(Active Directory). We have built a separate application to manage user's login name and password. Now we want to take advantage of the password management shipping with Luminis 5.1 and allow users to change their credentials in Luminis, and then the new data will be written back to external LDAP server. Unfortunately, according to Ellucian support and their documentation, this is not doable in current system. We wonder if any school has somehow implemented the similar idea before. Any suggestion would be welcome and very much appreciated!
