Did your ntlm authentification work fine ? How did you configure it ? With Samba/Winbind ?

Error returned 'BH gss_acquire_cred() failed: Unspecified GSS failure. Minor code may provide more information. Unknown error' I followed the manual on http://wiki.squid-cache.org/ConfigExamples/Authenticate/Kerberos. Everything worked fine an I created the HTTP.keytab with the msktutil. I checked all with [root@http-proxy /]# kinit -V -k -t /etc/squid/HTTP.keytab HTTP/http-proxy.justiz.niedersachsen.de Using default cache: /tmp/krb5cc_0 Using principal: HTTP/http-proxy.justiz.niedersachsen.de@xxxxxxxxxxxxxxxxxxxxxxx Using keytab: /etc/squid/HTTP.keytab Authenticated to Kerberos v5 So I have no idea what I'm doing wrong. Is there any other way to troubleshoot the problem. ???? Thank you Ralph
