In Mango 3.6, is it possible to use LDAP for authentication purpose?
LDAP for authentication
To my knowledge, not at this time. The users are stored in the mango database as there are distinct permissions they need to inherit for it (the dashboard) to work.
If you were to write an API that handles all of the login part and talks to the mango users api to gain access to the dashboard then maybe you can arrange something. Otherwise, no.
