An existing User Directory Connector (UDC) stopped working.
The following error is displayed:
The User Directory Connector (UDC) is not configured because the following error occurred. Setting up connection to LDAP root node failed. Check log file
Configuring an identical connector with the same parameters on another server is working fine.
When starting a sync, the following exception is thrown in the User Repository logs:

Environments:
LDAP filter strings are stored for UDC. If the LDAP filter is removed from the database (by using pgadmin, for example), leaving the string as a null value rather than an empty string, the Qlik Sense Services will not be able to correctly interact with the UDC anymore.
Resolution:
- Open the Qlik Sense Management Console
- Navigate to User Directory Connectors
- Open the UDC showing the symtomps
- In the empty LDAP filter field, enter any values
- Confirm the changes
