Subject: Introduce the UserIdentity interface.
X-Git-Tag: 1.31.0-rc.0~1465
X-Git-Url: http://git.cyclocoop.org/?a=commitdiff_plain;h=38edb8ab30d21e67e69871582e34b5120cbcc33a;p=lhc%2Fweb%2Fwiklou.git

Introduce the UserIdentity interface.

This provides a narrow view on a user identity, providing access to
ID and name.

This has been extracted from I140f43a6fb443b for re-use with Actors,
on Anomie's request.
