we had some issues with ldap login, and had to create a temporary login to access the system.

after recreating a ldap/hybrid identity provider, all the sensors for our project have “null” and exclamation marks.

is there a setting we have missed to get everything up and running as normal again?

The authentication issues seem like a red herring.

This looks more like a run of the mill configuration error. Consider getting in contact with support.
