What I do have is: 1) squid_kerb_auth 2) basic auth using ntlm_auth 3) group lookups using wbinfo_group We are running samba on the proxies and samba is bound to AD, for kerberos we use a keytab that contains entries for our load balancer and the machine SPNs, I manually generate these keytabs on the windows server, transfer them over and use ktutil to merge them into a single keytab file. All I can say is about 1 in 1000 password changes triggers something that causes one user to continually get locked out until we restart squid on the machine causing the password errors according to AD. -- Brett Lymn "Warning: The information contained in this email and any attached files is confidential to BAE Systems Australia.
