[K12OSN] Login in more than one place?

[Paul Lemke]

Hello, 

I didn't know if this is true or not because I haven't been to the school
yet... but one of the teachers tried to log into a pc, then log into a
laptop to use a projector and he couldn't. Is this the default for an
samba/ldap setup? If so... how would I be able to change it so that people
can log into more than one pc at a time? 
Thanks!
Paul
