Let me guess: UID->username is a libc function...
Problem is you can't always map a UID to a username under Unix. The
username is not always in the /etc/passwd file. You can have LDAP (I
think that's what it's called), Kerberos etc... users. I noticed the
same problem in fpGUI's file dialogs. So I wrapped that code in
try..except calls. Try the local user (in /etc/passwd), if it fails to
resolve, fall back to using the UID as is. On standard desktop linux
this is 99% of the times ok, but in a large corporate environment
things might be different.
I haven't thought about "network users", so thank you Graeme and Jonas
for the explanation.
Either way, using the UID should be fine too...or better that it currently is.
That's why I suggested at the end to provide a OnGetTempDir besides the
OnGetTempFilename, so that only a part (e.g. tmp dir resolving) of
GetTempFilename can be replaced.

Sven
