[pmwiki-users] Check for a specific user name

[K. Buehler]

Hello,
I need something like

(:if expr auth admin || auth attr || auth edit :)
[[Logout -> {$Name}?action=logout]]
(:if:) 

I found on http://pmwiki.org/wiki/PmWiki/ConditionalMarkup,
but after about an hour searching in the mailinglist and
the cookbooks I did not find what I searched.

The use case: I would like to check for a special User Name e.g. over
{$AuthId} (which is installed). If that user is logged in I would like
to show a special link.

Any solution how to solve this?

Thanks in advance for an answer on this!!
