You'll need the development files for Kerberos. Yast will get them for you as in the screenshot here.

I saved it in Downloads. so it's:
tar -xzvf kstart-4.1.tar.gz
(now become root)
(now become not root again)
You'll find k5start in /usr/local/bin so just typing k5start will launch it.
An example of using it is for processes that run all the time and who's Kerberos ticket would normally expire, so the guy getting the ticket must have renwable enabled. I needed to keep nslcd alive via GSSAPI to access the LDAP in Samba 4. k5start saved my life!
k5start -v -f /etc/nslcd.keytab -U -o nslcd-user -K 360 -k /tmp/krb5cc_0
