After upgrading from 4.0 EAP 7757 to 4.0 final TC is not able to check out from our Subversion repository (Subversion 1.5.0, Apache 2.2.9, HTTP, SSPI auth). The error message is "svn: OPTIONS of '/svn-prod/repository/trunk': 403 Forbidden". I've verified that all VCS settings (URL, user, password) are correct. Looking at the Apache HTTP access log it's obvious that TC doesn't send user credentials at all:
172.26.16.143 - "" [02/Dec/2008:21:54:04 +0100] "OPTIONS /svn-prod/repository/trunk HTTP/1.1" 403 227
I've tried other Subversion users (including my own Subversion user) without success. Do you have an idea about what's going on?
