Connector not recognize kerberos token

Hi,
I have a enterprise connection configured with the name ADBBM.
I’ve installed the connector and it’s working fine within the LDAP config, I can log in with the AD users via universal login, but when I enable the kerberos option and click “Try” it send me to the connector url:port/wsfed?prompt=consent&wprompt=consent&wctx=xr4LNTFZH_ssETBa67YpAAgXYxQOoL84&wtrealm=urn%3Aauth0%3Adev-phbueno&wa=wsignin1.0&wreply=https%3A%2F%2Fdev-phbueno.auth0.com%2Flogin%2Fcallback), but there is a the name of my enterprise connection(ADBBM) and asks me for a user/password and none of the users/pass works there.
I’m in the AD domain and the same network.
Here is my connector config.json

{
“LDAP_BASE”: “DC=clientesmentores,DC=com,DC=br”,
“LDAP_URL”: “ldap://localhost”,
“ANONYMOUS_SEARCH_ENABLED”: false,
“AD_HUB”: “XXXX”,

“LDAP_USER_BY_NAME”: “(sAMAccountName={0})”,
“HTTP_PROXY”: “”,

}
Anyone knows what can be happening here?

Thanks in advance.
