mounting cifs using kerberos not getting ticket

I'm trying to mount shares on Ubuntu using Kerberos authentication, after logging using an AD account, klist outputs the following

Ticket cache: FILE:/tmp/krb5cc_1320813139_Ipmgx6Default principal: XXXX@XXX.GRPValid starting       Expires              Service principal06.09.2022 14:15:58  07.09.2022 00:15:58  krbtgt/XXXX.GRP@XXX.GRP    renew until 07.09.2022 14:15:58

I can also list the shares using smbclient -k -L XXXX.com.

I'm using this script to do the mounting:

#!/bin/bashuser=$(whoami)cruid=$(whoami)gid=$(id -g $user)uid=$(id -u $user)sudo mkdir /home/testsudo mount --verbose -t cifs -o user=$user,cruid=$user,sec=krb5,gid=$gid,uid=$uid,vers=3.0 //XXX.com/XXXX /home/test

it outputs the following error: :q

mount error(126): Required key not available

here is a look into /var/log/syslog

I tried everything, nothing seems to fix this problem, can someone help me even with an idea?
