/** <module> User profile configuration

Configure  maintenance  of  user  profiles.  This  config  file  may  be
optionally enabled if one  or   more,  notably federated, authentication
modules are loaded. It maintains a database of identified users.

The user profile infra structure depends on the pack _profile_, which is
linked to SWISH as a git submodule.  To use profiles, run

    ```
    git submodule update --init pack/profile
    ```
