com.atlassian.crowd.exception.OperationFailedException: java.util.concurrent.ExecutionException: com.atlassian.crowd.exception.OperationFailedException: org.springframework.ldap.InvalidSearchFilterException: Empty filter; nested exception is javax.naming.directory.InvalidSearchFilterException: Empty filter; remaining name 'DC=example,DC=com'Cause
One of the following fields is blank:
User Object Filter
Group Object Filter
Roles are enabled. This has been deprecated for quite some time and should always be disabled.
Resolution
For Cause 1
Edit the LDAP directory configuration and populate the offending field as necessary. More information on the fields here: Connecting to an LDAP Directory
For Cause 2
Create a new LDAP directory. By default, the ldap.roles.disabled will be set to true.
Otherwise, disable Roles in your current LDAP directory configuration. As there is no way to do this in the interface, this will require manual database edits. Here is the SQL query to return that attribute's information:
⚠️Backup your database first
1select * from cwd_directory_attribute where attribute_name = 'ldap.roles.disabled';Notice that the attribute_value column is showing false
You'll want to run an update statement to set the attribute_value to true
