File Access Security

AcuServer allows users of UNIX networks to choose between the system security that AcuServer offers and the security features offered by their own operating system. By default, AcuServer system security is used to govern file access.

If you use AcuServer security, the AcuAccess and AcuAccess.vix files are used to establish user access privileges. Remember that these two files must be readable and writable only by Administrator and System, or AcuServer will not start.

Note: If you experience a problem with file access, it can be helpful to give the users Full Control of the files and directories they need to use. After everything is working smoothly, reduce access to Read-Only if desired. However, be sure to test each program to make sure that everything continues to function as you expect with the reduced privileges.

If you prefer to use UNIX security mechanisms, you may do so by setting the configuration variable SECURITY_METHOD to LOGON in both the runtime configuration file and server configuration file. See Server Configuration Variables for more information about the SECURITY_METHOD configuration variable.

Note that if you decide to use UNIX security instead of AcuServer system security, your users will have whatever permissions the system administrator has set up for them.
