Error Testing LDAP Authentication: Write operations are not allowed in read-only mode (FlushMode.NEVER):

When connecting MS LDAP server with settings that work fine with JIRA 5 I get the following error.

Test user can authenticate : Failed
Write operations are not allowed in read-only mode (FlushMode.NEVER): Turn your Session into FlushMode.AUTO or remove 'readOnly' marker from transaction definition.

Steps to reproduce

1. Set up LDAP directory in Confluence Admin
2. Enter a user and test their authentication
3. Error message will appear
4. Synchronise the directory and note that the user is created
5. Log in as the user, this will be successful

Resolution

This error message occurs despite the authentication test being successful. It does not indicate an actual error in authentication, and no functionality is affected. You can safely continue to configure the LDAP directory and it will be successful.
