Im wondering why you dont use winbind for the keytabs setup and let samba handle it. 
 
Thats what i suggest. 
Install winbind only. 

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

    # renew the kerberos ticket
    winbind refresh tickets = yes

Add the use that keytab or make separated keytab file as you do now. 

You might have a reason to use k5start but i havent see it so far. 

Greetz, 

Louis
