Hello Firebird Gurus

We have just upgraded our Firebird server from 1.5 to 1.5.3
and we have encountered well known UDF location problem. Old server was
uninstalled first before installing new version.

(error stating that access udflib.so is denied by server administrator or
something like that)

We have tried putting full path to fiebird root directory (standard
/opt/firebird) than putting full path to UDF directory. No succes.

Is there any simple solution for that?? The only thing I haven't tried is
setting udfaccess to full because as I remember it requires full path to the
library in udf declaration.

TIA
Marcin
