[horde] Redirected to 127.0.0.1

[P.G. Willemsen]

I can access http://localhost/horde and http://localhost/horde/imp and 
login succesfully.

When I try this from another PC in the network, http://10.0.0.150/horde 
redirects me to http://127.0.0.1/horde, which obviously does not work, 
as horde is not installed on the pc I would like to access 10.0.0.150 from.

http://10.0.0.150 works nice.

I expect it's just a setting, but where...?

Kind regards,
Peter Willemsen
