LDAP Authentication not working after upgrade from JON 2.3.1 to 2.4

Issue

• After upgrading from 2.3.1 to 2.4, LDAP Authentication against our active directory server is no longer working and the rhqadmin password has reset to it's default value.

• I validated that the AD server is working correctly in our staging environment by configuring it to authenticate against production and it worked correctly.

• I have tried reentering the correct LDAP Authentication information in production, but it still does not work correctly (but has been displayed correctly the whole time).

• No other JON functionality seems to be impacted when I looked around in the rhqadmin account, but users still cannot log in.
