-      * Set cyrusauth module to use it: ''/msg *cyrusauth cloneuser yourcloneusernamehere'' +      * Configure this user how you want them. Mainly use your above zncadmin account to disable their flag access to bind. 
-      * Let it create users: ''/msg *cyrusauth createuser Yes''+    * Configure cyrusauth module: (''/msg *cyrusauth help'')

 +      * Let it create users: ''createuser Yes'' 
 +      * Your services/ircd need to provide an account to auth as, which can set the users account on IRC (Impersonization). In X3/nefarious this is the I flag in authserv. Create an account with this flag and set its details here: ''setimpersonateaccount znc somepassword'' 
 +      * A network to configure for cloned users: ''setNetworkName yournetwork''

 +      * Set <username> <password>: Not used, dont set this 
 + 
 +===== Setup IRCD ===== 
 +  * Add a webIRC line: 
 + 
 +  WebIRC { 
 +    description = "znc"; 
 +    host = "*@zncip"; 
 +    pass = "crypted password"; 
 +  }; 
 +   
 +  * Except block to protect znc from flood limits: 
 + 
 +  Except { 
 +    host = "*@zncip"; 
 +    gline = yes; 
 +    rdns = yes; 
 +    ipcheck = yes; 
 +    targetlimit = yes; 
 +  };

 +===== Security ===== 
 +I run this script after ''make install'' to disable a bunch of the plugins:
