registration of new users in xwiki from external application : appropriate rights not set

Hello xwiki developpers Imagine you had to powerful applications. First xwiki, then discourse engine for deliberative decision making. Lets call the latter 'dito'. Imagine how nice it would be, 1: if these two applications could use the same authentication, and if 2: signing into one aplication would sign you into the second, too. 3: registering a new account in dito would add a new user to xwiki with the appropriate rights (edit) without admin interaction (explicitly setting rights) needed @1: Done! Fortunately, as far as *authentication* is concerned, xwiki makes a geeks life easier, as it provides a XWikiAuthService interface. Which I implemented for my needs and which works fine. @2: Hm, solve 3 first @3: Stuck! Unfortunately, as far as *authorisation* is concerned, I did not yet get the point. My approach is to make an xml-rpc, that logs into the wiki (with a user that i added manually and that has admin rights) and calls the XWiki.createUser() method. In order to achieve that, i extended the ConfluenceRpcHandler and added a method createUserFromExternal Suddenly, I get an error in Xwiki, approx. line 2570(i.e. methods system.out.println("xwiki create user : !context.getUtil().match"+xwikiname);returns -4 :) try { if (!context .getUtil() .match( this.Param( "xwiki.validusername", "/^[a-zA-Z0-9_]+$/"), xwikiname)) { return -4; } } As i am calling from external, the context object (and the request, it is carrying) are not as complete as they are, when i register via the xwiki web page. My questions are: - is it a good idea to do xwiki user registration automatically and from external *that* way? do you know alternatives? - is there an implementation of the mehtod: /** * {@inheritDoc} * @see ConfluenceRpcInterface#addUser(String, java.util.Map, String) */ public void addUser(String token, Map user, String password) throws XWikiException { throw new XWikiException(XWikiException.MODULE_XWIKI_XMLRPC, XWikiException.ERROR_XWIKI_NOT_IMPLEMENTED, "Not implemented"); } ? - If you integrate xwiki into other environments or vice versa, what is the best practice to wire the two different registration and login processes of both, xwiki and some_app ? Of course, i searched the archives, but no solution for this so far... Any hints?
