Basic login works only first time

[nestle2377]

Hi, I'm implementing the mod_auth_gssapi and it works fine. I've a strange behaviour with chrome and basic login (when the client is not on domain).
when the pop-up appears If I insert the correct credential the first time I'm succesfully logged in. If I type a wrong credential the pop-up appears again but now even I insert the correct credential I can't enter.

on the logs when this happen I've this entry:

[Thu Mar 11 10:09:29.699735 2021] [auth_gssapi:debug] [pid 79110:tid 140125019256576] mod_auth_gssapi.c(870): [client 10.211.30.219:56612] URI: /dominio/sigma/app/, no main, no prev

is strange that says that has no support for encryption type since it works in the first attempt.

this is my configuration:

    AuthType GSSAPI
    AuthName "GSSAPI Single Sign On Login"
    GssapiBasicAuth On
    KrbServiceName Any
    GssapiUseSessions On
   GssapiSessionKey key:<RANDOM>
    Session On
    SessionCookieName gssapi_session path=/dominio;domain=intranet.servizi;httponly;secure;
    GssapiCredStore keytab:/var/www/html/rf002/conf/sa_RF002-KRB-Svil.keytab
    Require valid-user

my krb5.conf:

[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]

 dns_lookup_kdc = true

 kdc = sisnodc02.sistemi.group
}

[domain_realm]

[capaths]
SEDI-DIREZIONI.GROUP = {

}

and my keytab:

slot KVNO Principal

any idea?

thanks!
