Its only that "packaged" samba does support sssd but then you will use the "older" samba versions. 
If you using up2date packages from my repo, you cant use sssd, not supported. 

Well, if you cache all you logins correctly, you should be able to login the laptop. 
Basti its first messages showed .. If VPN.. And assuming VPN, you must have network. 
And yes, the network-online.target might be overkill if you dont use/have network at all,
but it long ago that i seen people working without internet/network connection.

Only, you need to increase all cache time values where needed, like. 
Why i add the Kerberos parts also, because its used, that simple. 

winbind cache time (G) ( default 5 min )  increase to x days at least. 
Change the kerberos cache location through the variable : KRB5CCNAME=DIR:/mydir/

But there is most probely more you need to set to integrate it all. 
That can be found in `man pam_krb5`
