Looping Squid Auth

[grinderfurax]

Hello.
After 3 days of tries and search, I finally post a thread to find some help here…
I have a Squid / Squidguard that works perfectly since a couple of weeks.
Now I'm trying to add a captive portal with the Squid Auth Settings.

First I tried a local database with some users, it's ok. But I've got 1500+ users inside a Win2012R2 AD, then I tried both "NT Domain" and "LDAP" auth.

Not sure if I have something to configure inside windows part... but I tried Squid with these settings :

LDAP version 3
server : ipadress
port : 389
LDAP server user DN : cn=ldap,cn=users,dc=xx,dc=yy
LDAP password : xxxxxx
LDAP base domain : dc=xx,dc=yy
LDAP username DN attribute : uid
LDAP search filter : sAMAccountName=%s

I tried with NT domain settings :
server : ipadress
NT domain : xx.yy
secondary NT servers : ipadress2

In both case, the captive portal keeps looping asking my credentials...

Any help please ?
