Hi,
i have a problem with my SLES11SP1 Webserver. I want to use the Kerberos authentication for SingleSignOn between my Windows ADS, Windows Client and Linux Webserver. I have the /etc/krb5.conf configured and pushed the Kerberos Ticket from my Windows ADS on the Linux Webserver. I also protected my DocumentRoot with a .htaccess file. Now i want to access the webserver and get a 401 error message. In the http trace i can't see the entry "WWW-Authenticate: Negotiate" in the header.
A look into a functioning server errorlog shows me the following:
[Tue Aug 16 10:23:18 2011] [debug] src/mod_auth_kerb.c(1277): [client 10.43.2.33] Acquiring creds for HTTP@entintranet2.wl

The errorlog of the faulty server is empty. Only in the access log I see one 401 messages:
10.43.2.33 - - [16/Aug/2011:10:47:12 +0200] "GET / HTTP/1.1" 401 1432 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2.18) Gecko/20110614 BTRS28059 Firefox/3.6.18"
It looks as if the Kerberos module is not used by the Apache.
