Yes, I had the session bound to seat0.
Configuring lightdm to use an empty seat made the session Active=yes.

$ loginctl show-session c37
Id=c37
Timestamp=Вт 2013-11-05 12:22:13 MSK
TimestampMonotonic=59464298414
VTNr=0
Display=localhost:10
Remote=no
Service=lightdm
Scope=session-c37.scope
Leader=25926
Audit=0
Type=x11
Class=user
Active=yes
State=active
IdleHint=no
IdleSinceHint=0
IdleSinceHintMonotonic=0
Name=intelfx

However, this still isn't exactly what I want. Now the session has no seat, so
1. udisks does not allow me to mount removables without authentication;
2. I suppose the dynamic device node permission stuff won't work for me either.

So I want that session to be equivalent to a local one in terms of permissions etc...
Is it somehow possible?

Thanks,
