Hello,
I have just installed Projeqtor this morning on a Windows 2012R2 server.
We have an MS active directory domain. So I try to configure it :
I have put :
dc=mydomain,dc=fr
myadserver.mydomain.fr
389
version 3

I have also created in the AD a dedicated user : projeqtor
for the filter I have put :
sAMAccountName=%USERNAME%

When I try to make connection with a member of the domain, I have this lines in the logs :

2020-02-20 14:40:59.934 ----- DEBUG ----- loginCheck : current db version = 'V8.3.4'
2020-02-20 14:40:59.936 ----- DEBUG ----- User->authenticate('p.nom', 'NgPvDmuMTl5AxiurcN+nyJI=')

2020-02-20 14:40:59.947 ** ERROR ***** [V8.3.4] cause = ldap_bind(): Unable to bind to server: Invalid credentials

The firewall if off on the Projeqtor server.
On the AD, when I have a look at my users, I have seen that the value sAMAccountName corresponds at the user login.

I don't know what to do more. 🙁
To activate debug, is it in the parameters.php file ? with this values :
$logLevel='7';
$paramDebugMode='true';
