Returning a Borrowed License Early
To return a borrowed license early, first reconnect the borrowing system back to the network
and then, from the same machine that initiated the borrowing, issue the command:
lmborrow -return [-fqdn][-c license_file_list] [-c display] feature
where:
-fqdn Directs lmborrow to access the borrowing system
using its fully qualified host name. Use this option if
the license was borrowed based on the fully qualified
host name, rather than the relative distinguished name.
Use lmstat to determine the format of the host name
used when the license was borrowed.

Returning the license early has the effect of clearing the LM_BORROW setting for the vendor
daemon that serves the returned license.
If the borrowing system is not placed back on the network before attempting the early return,
the license is not returned and LM_BORROW is kept intact. Additionally, an error message is
issued to the end user with notification that the system needs to be connected to the network.
