The variable DEFAULT-UMASK defines the file creation mask (umask) to be used for users whose umask has not been adequately defined in the AcuAccess file (i.e., their umask was set to spaces). The default value is "000", which causes all files created by these users to be readable and writable by everyone. You can change DEFAULT-UMASK to provide whatever read/write permissions you desire for these undefined users. Valid values include any octal value between 000 and 777.
