Why do I receive a "License Administrator (-63)" error when trying to return a borrowed license key?

When trying to return a borrowed license key, I get the following error:

"lmborrow: You are not a license administrator. (-63,199)"

The prompt is returned but the borrowed key remains checked out of the license pool. How can I return a license early?

This error results when the 'lmremove' feature is disabled on the network license manager by starting the license manager by using the '-2 -p' flag. When set in this manner, it restricts usage of lmdown, lmreread, and lmremove to a license administrator who is by default root. If there a UNIX group called lmadmin, then use is restricted to only members of that group. If root is not a member of this group, then root does not have permission to use any of the above utilities. If -2 -p is used when starting lmgrd, no user on Windows can shut down the license server with lmdown.

In order to be able to return a license early, each user who will borrow will need to be added to the lmadmin group. Alternatively, you can restrict only the 'lmdown' functionality. This can be done with the '-x lmdown' flag which turns off lmdown or '-local' which restricts lmdown to the local machine only. For example:

lmgrd -c license.dat -l /var/tmp/lm_TMW.log -x lmdown

lmgrd -c license.dat -l /var/tmp/lm_TMW.log -local

For more information about these flags see the "lmgrd Command-Line Syntax" section of the FlexNet License Administration guide.
