    • init

      public void init(String name, String implName, AuthManagerConfig config) throws EBaseException
      Initializes the UidPwdDirBasedAuthentication auth manager. Takes the following configuration parameters: 
              ldap.basedn             - the ldap base dn.
        ldap.ldapconn.host      - the ldap host.
        ldap.ldapconn.port      - the ldap port
        ldap.ldapconn.secureConn - whether port should be secure
        ldap.minConns           - minimum connections
        ldap.maxConns           - max connections
        dnpattern               - dn pattern.

      dnpattern is a string representing a subject name pattern to formulate from the directory attributes and entry dn. If empty or not set, the ldap entry DN will be used as the certificate subject name.

      The syntax is 

           dnpattern = SubjectNameComp *[ "," SubjectNameComp ]

     SubjectNameComponent = DnComp | EntryComp | ConstantComp
     DnComp = CertAttr "=" "$dn" "." DnAttr "." Num
     EntryComp = CertAttr "=" "$attr" "." EntryAttr "." Num
     ConstantComp = CertAttr "=" Constant
     DnAttr    =  an attribute in the Ldap entry dn
     EntryAttr =  an attribute in the Ldap entry
     CertAttr  =  a Component in the Certificate Subject Name
                  (multiple AVA in one RDN not supported)
     Num       =  the nth value of tha attribute  in the dn or entry.
     Constant  =  Constant String, with any accepted ldap string value.

      Example: 

       dnpattern:
     E=$attr.mail.1, CN=$attr.cn, OU=$attr.ou.2, O=$dn.o, C=US
 
      
 Ldap entry dn:
     UID=joesmith, OU=people, O=Acme.com
 
      
 Ldap attributes:
     cn: Joe Smith
     sn: Smith
     mail: joesmith@acme.com
     mail: joesmith@redhat.com
     ou: people
     ou: IS
     etc.

      The subject name formulated in the cert will be : 

         E=joesmith@acme.com, CN=Joe Smith, OU=Human Resources, O=Acme.com, C=US

      E = the first 'mail' ldap attribute value in user's entry - joesmithe@acme.com
      CN = the (first) 'cn' ldap attribute value in the user's entry - Joe Smith
      OU = the second 'ou' value in the ldap entry - IS
      O = the (first) 'o' value in the user's entry DN - "Acme.com"
      C = the constant string "US"

    • getExtendedPluginInfo

      public String[] getExtendedPluginInfo(Locale locale)
      Description copied from interface: IExtendedPluginInfo
      This method returns an array of strings. Each element of the array represents a configurable parameter, or some other meta-info (such as help-token) there is an entry indexed on that parameter name Where: type_info is either 'string', 'number', 'boolean', 'password' or 'choice(ch1,ch2,ch3,...)' If the marker 'required' is included after the type_info, the parameter will has some visually distinctive marking in the UI. 'description' is a short sentence describing the parameter 'choice' is rendered as a drop-down list. The first parameter in the list will be activated by default 'boolean' is rendered as a checkbox. The resulting parameter will be either 'true' or 'false' 'string' allows any characters 'number' allows only numbers 'password' is rendered as a password field (the characters are replaced with *'s when being types. This parameter is not passed through to the plugin. It is instead inserted directly into the password cache keyed on the instance name. The value of the parameter 'bindPWPrompt' (see example below) is set to the key. In addition to the configurable parameters, the following magic parameters may be defined: HELP_TOKEN;helptoken - a pointer to the online manual section for this plugin HELP_TEXT;helptext - a general help string describing the plugin For example: "username;string;The username you wish to login as" "bindPWPrompt;password;Enter password to bind as above user with" "algorithm;choice(RSA,DSA);Which algorithm do you want to use" "enable;boolean;Do you want to run this plugin" "port;number;Which port number do you want to use"
