Hi, I did an update to svn 1.8.9 on our server yesterday and am now running into problems whilst updating the corresponding windows client.
Server details: CentOS 6.5 x64 SVN 1.8.9, compiled on my own Apache 2.2.15 Authentication using mod_auth_kerb to windows domain Client: Windows Server 2008 TSVN 1.7.13 Everything ran fine so far. I then upgraded to TSVN 1.8.7 which ships with svn 1.8.9 binaries. Now, on every repository involving action I get kerberos errors in my apache log: [Tue Jul 08 15:08:10 2014] [error] [client 192.168.1.152] gss_accept_sec_context() failed: No credentials were supplied, or the credentials were unavailable or inaccessible (, Unknown error) Strange thing is, TSVN works fine from a user perspective (no error displayed whatsoever...). I then tried to use the svn command line binaries, same result, evrythings works, but apache error log is DOSed with these error entries. I tried to either "prefer" or deny BulkUpdates on the server, nothing changes. Since subversion 1.8 comes with serf, it might have do to with the way serf handles kerberos. >From the linux cmd (on the svn server itself), I can use kerberos (kinit + svn command afterwards) just fine, without any errors popping up in the apache log. Our browsers (IE, Chrome, FF) worked fine all the time using kerberos, before and after upgrading svn on the server. TSVN 1.7.13 works as well, so do the svn binaries shipped this version. I'm quite stuck, because I do not know where to start. To my mind kerberos is set up correctly because all clients work, except svn 1.8 I thought I could solve the problem by falling back to BulkUpdate, but it does not seem to help. Any suggestions are appreciated!
