Ssowat credentials active directory


Hi, because the coronavirus I need to give access to our intranet across Internet. I’m trying to use ssowat to have SSO using LDAP. ¿Where can I configure which user ssowat use to authenticate in ldap server? I’m using active directory. I always get invalid credentials error.
I’m desperate trying to make it work, thanks in advance.

The Domain controller receive this request:
415 7.247887 LDAP 139 bindRequest(1) “sAMAccountName=testUser,CN=Users,DC=test,DC=local” simple
and the server returns this:
416 7.248683 LDAP 176 bindResponse(1) invalidCredentials (80090308: LdapErr: DSID-0C09042F, comment: AcceptSecurityContext error, data 52e, v2580)
