Need help configuring AWX (Ansible Tower) with on-premise LDAP

AWX is installed but I’m struggling with the LDAP authentication config for users. For this exercise I would like to allow members of the “AWX Tower Users” group to log into the AWX console, where their AWX username is sAMAccountName:

LDAP SERVER URL: ldap://dc1.company.com:389

LDAP BIND DN: CN=svcacct,CN=Users,DC=company,DC=com

LDAP BIND PASSWORD: (password entered here)

LDAP GROUP TYPE: MemberDNGroupType (the default setting)

LDAP REQUIRE GROUP: CN=AWX Tower Users,OU=Groups,DC=company,DC=com

The only other thing that has any input was by default:

LDAP GROUP TYPE PARAMETERS:

{
 “member_attr”: “member”,
 “name_attr”: “cn”
}

Attempts to log in with my sAMAccountName as the username result in error: Invalid username and/or password. Please try again.

Can someone help a newbie?
