Secure SSL flag does not work when using Delegated LDAP

Summary

The Secure SSL flag under the Advanced Settings section in the LDAP settings does not work when using Delegated LDAP/Internal with LDAP Authentication in JIRA.

Steps to Reproduce

1. Add a Delegated LDAP (AD) in JIRA
2. Checking the Secure SSL checkbox and hit the Save and Test button
3. if we edit the LDAP directory again and verify that option, it will no longer be checked

Expected Results

• The option should stay checked and the database should get updated with that option checked.

Actual Results

• The option is not checked if we access the directory settings again and the database does not update the ldap.secure attribute. Update/insert the value directly in the database will not make the option appear checked in the interface.
