[7.306] http-proxy auth. failed (clock skew too great)

Hi,

i used the http proxy with AD SSO. After some time many clients get an "authentication failed" if surft to a site.

httpd.log
(none) httpproxy[3745]: [ 0x807af40] adir_auth_process_negotiate (auth_adir.c:298) gss_accept_sec_context: Clock skew too great


Disable/Enable the proxy, flush the authentication cache, ... did not resolve this. Only restart of asg btw. restart of client, helps.

Any ideas?

  • Hi, 

    please check the time difference between the ASG and your Active directory Server. 
    You are using Kerberos, which is issuing time limited tickets. 

    If the two systems are not in time sync, than you might see such problems.

    regards
