Like many other Atlassian tools, Bitbucket should support configuring the crowd directory from the crowd.properties file.

Currently, it seems that all of the crowd directory configuration is stored in the database and can only be configured with the Administrator UI.

Would also like to note that the password is stored in plain-text in the database – which is just bad practice.. tsk tsk

Please consider adding support for the crowd.properties file for added consistency of configuration across the suite of tools.
