Not single sign on (that is Kerberos), but unified (one) login.

No, three times. Your "UNIX" password crypt in userpassword and twice
for cifs: once as an NT hash (MD5?) and one as a LANMAN hash. It works
out fine - just change your passwords via Samba or use the standard
change-password extended operation [LDAP] with the smbk5 module and they
will all be updated simultaneously.

No.

Yep.
