Apache Druid

you should check the router logs for any errors.

Unfortunately no ERRORs, people able to access but don’t see anything in the dashboard.

Resolved the issue (not related to Druid itself :slightly_smiling_face: )
Enabled debug logs for LdapRoleProvider and found following:

```2023-03-22T12:27:34,343 DEBUG [qtp1608217492-138] org.apache.druid.security.basic.authorization.LDAPRoleProvider - No memberOf attributes

We found after some `ldapsearch` games, that LDAP bind user that was created by our IT from some reason didn’t return :expressionless:
```memberOf attributes```
Worked with other user.
