According to the documentation of nfsmapid
It is possible to create your custom resolver by adding a line like this
create id_resolver uid:* * /some/other/program %k %d
In the file
So I created a test script that simply creates a file that prints %k %d to a local text file just o see how this would work. As I understand it each time a request for some UID or GID is generated (by doing ls -la, for example) it should invoke my script. Is this not the case?
Should I restart some service in order to get this to work? Also how would I return the value (string) of the UID or GID that is being queried?
