Issue Summary

This is reproducible on Data Center: yes

Steps to Reproduce

1. Create an LDAP Directory and select Read Only, with Local Groups; 
2. Set a test group in the Default Group Memberships field, example, jira-software-users;
3. Save the LDAP configuration;
4. Edit the LDAP configuration again and remove the value from the Default Group Memberships field; 
5. Save the configuration. 

Expected Results

The Default Group Memberships field will be cleared.

Actual Results

The Default Group Memberships field is still with the group value. 

Workaround

There is a workaround to manually remove this value from the Jira database, but we recommend that you first perform this approach on a test instance first and create a backup of the database.

1. Stop Jira;
2. Create a database backup;
3. Run the following SQL query in order to find the affected directory ID:

   select * from cwd_directory;
   

4. With the ID from step 3, run the following query in order to clean the Default Group Memberships field:

   update cwd_directory_attribute set attribute_value= NULL where directory_id= <ID_FROM_STEP_3> and attribute_name='autoAddGroups';
   

5. Start Jira
