[squid-users] microsoft edge and proxy auth not working

[Mike Surcouf]

Are the browsing machines domain joined?
If so and you are just talking about joining the squid proxies to the domains for auth delegation to the dcs this is greatly simplified with realmd now.
Could probably be scripted quite easily.

Kerberos is on the wishlist for very long. 
one reason was: the setup is a bit complicated and we do have 150 proxies in our subsidiaries. so we need 150 different Kerberos setups with 150 trusts and tickets and certificates etc. so we work on this to have it someday replaced...
