It really should only affect the Well known SIDs etc, it shouldn't
affect your users & groups, but it might, this is no reason to not fix

It seems as if your kerberos ticket is expiring, so if winbind isn't
set up correctly, this could be the cause of it not being renewed. The
only other difference between your smb.conf and mine, is that I also
have these two lines:

    dedicated keytab file = /etc/krb5.keytab
    kerberos method = secrets and keytab
