Sounds like good advice! 'squidauth' was just an example I was using for this forum. We have two AD accounts that we have created for these kinds of authentications so I cannot just easily go change the passwords yet I can request a new account. Both of those accounts though have long complex passwords with non alpha-numeric characters! I have always enclosed the passwords with single quotes to be safe yet that appears to have not helped and neither of these accounts/passwords have worked with the Squid basic_ldap_auth helper program. I will request the AD admin to create a new account with a password that only has the alpha-numeric characters and I will test that. Thx!
