OK, in that case I am now confused.

no squid_kerb_ldap. 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.
