I recently faced this error and was able to fix this by help of this page.
If you have changed the password of the super admin from /repository/conf/user-mgt.xml you need to change it in /repository/conf/jndi.properties as well.
One important thing that you need to take care of is that the special characters in passsword string in jndi.properties need to be encrypted. For example if password is admin?= in user-mgt.xml, you need to write it as admin%3F%3D in jndi.properties
