fbclient.dll changes the security descriptor of the calling process.

QA Status: Cannot be tested

 Description  « Hide
Using the fbclient dll (open an connection to an database) seems to change the security descriptor of the calling process.
For Example: If the process has granted the 'PROCESS_DUP_HANDLE' right, after opening an connection to the DB this right is no longer given.
This makes it impossible to have other processes to share handles to synchonization objects or other handles.

Maybe there is an SET_ACCESS instead of GRANT_ACCESS somewhere in the code.

The solution was incomplete and it didn't fix the problem, fbclient.dll v2.0.1 still changes the security descriptor of the calling process after opening a database. See the duplicate ticket CORE-1301.
