Title:
  remote login against UCCS server expects an email address as userid

Status in “unity-greeter” package in Ubuntu:
  New

Bug description:
  Hi,

  I am currently working on a non-Canonical UCCS session broker
  implementation [1] and I have stumbled over the requirement in unity-
  greeter that user IDs of remote logins have to be of an e-mail address
  format.

  While an e-mail address is indeed required for SSO against Launchad
  and thus against UCCS.landscape.canonical.com, this requirement is not
  very generic and a usability blocker in non-Canonical UCCS setups.

  With the X2Go project's UCCS implementation, users can in theory
  simply use (e.g.) an LDAP user ID (uid=foo) which works fine on the
  UCCS implementation side, but this user name »foo« will be rejected
  apriori by the e-mail format check code in /src/user-list.vala in
  unity-greeter.

  Attached is a diff against the current code that shows the position of
  the referred to code in user-list.vala. The patch  is _not_ a proposed
  solution, just a pointer to where in the code I am talking about (and
  indeed a dirty work-around that avoids this ungeneric error
  notification).

  My question is: are the unity-greeter developers open to  a more
  generic approach? E.g. making the RegExp in the e-mail check
  configurable in some config file (there is no unity-greeter.conf
  IMHO(?))? What approach would you prefer/suggest?

  If there is such an openness, I would love to support the team by
  providing such a patch? Will the effort be worth the invested time???

  Greets,
  Mike (from upstream X2Go) aka [email protected]
