SVN error: (501 Not Implemented) while creating dir

Hey, 
I'm trying to create a branches directory for our project: 
svn mkdir -m "Creating branches directory" http://local.domain/OoProject/branches 
But I got this error: 
svn: Server sent unexpected return value (501 Not Implemented) in response to OPTIONS request for 'http://local.domain/OoProject' 
I googled, it is a firewall issue. 
local.domain isn't guarded via a firewall. 
I turned the firewall off on my Mac client, but I got the same error. 
Any ideas? 
Thanks for help and time.
