We are using the UUID_CREATE() method from the UUIDLib.dll in our 'insert' stored procedures. When we run our application normally everything works fine. When we attempt to run unit tests from a test project, we get the following error:

FirebirdSql.Data.FirebirdClient.FbException : Access to UDF library "uuidlib.DLL" is denied by server administrator
----> FirebirdSql.Data.Common.IscException : Exception of type 'FirebirdSql.Data.Common.IscException' was thrown.
