4.4. I created a LIDS free session, but LIDS still appears to be active! What's wrong?

This can happen if you create an LFS on a virtual console and then switch to another virtual console and try to administer your machine. To clear it up, try enabling LIDS and then disabling it again (entering passwords when prompted):
# lidsadm -S -- +LIDS
# lidsadm -S -- -LIDS
NOTE: Be sure that there is no other administrator in an LFS because you will close his LFS!
