There are a number of additional configuration options, for logging and setting an SSL passphrase, that can be set in the file mf-server.dat, located in %ProgramFiles(x86)%\Micro Focus\Studio Enterprise Edition x.x\base\bin . These are mostly options that require setting before the Micro Focus Communication Server (MFCS) contacts the MF Directory Server. In the case of logging, this can be useful where there are problems with the connection between MFCS and MFDS. For instructions on the use of mf-server.dat to configure logging for MFCS, see the topics on securing communications in the Security section, or see the topic Communications Process Log Files in the Troubleshooting section.
