CIFS Mount over Domain Windows Share(AD)

My question is about about Red hat butn not having a subscrption i hope that someone of you can help me to understand about how to mount a Windows Domain based share with Red Hat 8.0. All the linux box are joined to the windows domain but a command that works with ubuntu does not work with Red Hat 8.0

In Ubuntu we sue the following command;

mount.cifs //domain/share /home/user/monut_point -o username=user,domain=mydomain,iocharset=utf8,uid=window_domain_id

This command, which works with ubuntu, does not work with Red hat 8.0 with the following error:

CIFS: VFS: \server Send error in SessSetup = -126
CIFS: VFS: Verify user has a krb5 ticket and keyutils is installed

So i presume in redhat i need to add the option sec=krbr5 which i don’t need in ubuntu,

Is that correct?

but how to manage automatically kerberos tickests

Thanks in advance
