Hello there,
I am having a similar issue to this. And in answer to Jeff’s question – our ambari server is setup for https, listening on port 8443. This seems relevant in some way otherwise I guess you wouldn’t be asking this question.
I have tried setting up ambari to authenticate via ldap (389) and ldaps (636) and receive the same error message.
I would also like to know if you have to run the ldap-sync command in order to authenticate users via LDAP? I had an ambari 1.6 install working, which would authenticate users from LDAP without having run the sync-ldap command. This does not seem to be the case with 1.7, where you seem to have to run the sync ldap command specifying both a user list and group list.
It seems like you need to know the users who will access Ambari in advance of setting up their access and that you are not able to simply specify a group membership, ie just use –groups and tell ambari to allow all members of a specific group access.
Many thanks.
