[horde] Current logged in user

[Peter Øgaard Meyland]

Hi list

I'm working on my own intranet with user specific settings, i.e. a book 
database and movie database. The intranet is displayed in a Horde Block 
on the main portal screen. I need to get the current logged in Horde 
user, so I can display the right intranet page for the user. I have the 
latest Horde Webmail Edition and I'm working with PHP as my server side 
language.

Can anyone show me the PHP code to get current logged in user?

TIA
Peter
