Hi, all, I am trying to install Dogtag Certificate System, but at the "PKI Subsystem Configuration", we have the problem at step: "Creat e a New Securit y Domain", whatever we enter, it display error "$errorString", and if we choose the "*Join an Existing Security Domain *", it display error "org.xml.sax.SAXParseException: The string "--" is not permitted within comments. Maybe some components or configure is error, but I setup and configure pki subsystem(include Requirements and runtime tool) by the site: http://pki.fedoraproject.org/wiki/PKI_Install_Guide , the infomation of my configure and environment: hostname: wotestca.com step 1: ============================================================ Starting pki-ca: [OK] pki-ca (pid 2817) is running ... 'pki-ca' must still be CONFIGURED! (see /var/log/pki-ca-install.log) Before proceeding with the configuration, make sure the firewall settings of this machine permit proper access to this subsystem. Please start the configuration by accessing: https://wotestca.com:9445/ca/admin/console/config/login?pin=HPQkcbu71yCYk... After configuration, the server can be operated by the command: /sbin/service pki-cad restart pki-ca ------------------------------------------------------------------------------------------------------------------------ step 2: open : " https://wotestca.com:9445/ca/admin/console/config/login?pin=HPQkcbu71yCYk... " to CA Setup Wizard step 3: choose "Create a New Security Domain", enter " testwosecdomain" and click "NEXT>" button, return errror"Invalid characters found in Security Domain Name testwosecdomain. Valid characters are A-Z, a-z, 0-9, dash and space" choose "Join an Existing Security Domain " , if enter "https://wotestca.com:9445" return error "org.xml.sax.SAXParseException: The string "--" is not permitted within comments" if enter" https://wotestca.com:9443" or " https://wotestca.com:9446" return error "Illegal SSL Admin HTTPS url value for the security domain " check the directory server: #service dirsrv status #dirsrv testca (pid 3342) is running...... So, we can't go on, please tell me what's the problem, and how to do? thanks a lot. -- Best Regards, jeff
