Can string remapping be disabled?
Yes, by using the –no-name-remapping option, however this should be considered an advanced option. Here is a brief rundown of OpenVPN’s current string types and the permitted character class for each string: X509 Names: Alphanumeric, underbar (‘_’), dash (‘-‘), dot (‘.’), at (‘@’), colon (‘:’), slash (‘/’), and equal (‘=’). Alphanumeric is defined as a character which will cause the C library isalnum() function to return true. Common Names: Alphanumeric, underbar (‘_’), dash (‘-‘), dot (‘.’), and at (‘@’). –auth-user-pass username: Same as Common Name, with one exception: starting with OpenVPN 2.0.1, the username is passed to the OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY plugin in its raw form, without string remapping. –auth-user-pass password: Any “printable” character except CR or LF. Printable is defined to be a character which will cause the C library isprint() function to return true. –client-config-dir filename as derived from common name or username: Alphanumeric, underbar (‘_’)
