Which value in the LDAP configuration will make email show as profile name when using Concourse.
If configuring a BOSH deployed Concourse, the displayed username is controlled by the ldap_auth.user_search_id_attr property in the Concourse deployment manifest.
If configuring a standalone Concourse deployment, then the displayed username is controlled by the `CONCOURSE_LDAP_USER_SEARCH_ID_ATTR` environment variable or the `--ldap-user-search-id-attr` command line parameter.
