Hi,
For Authentication Instead of j_security I had written my own servlet.And I am taking username and password from
User and setting that in request.In crud.xpl I am trying to acess this user name as below.
<include>/request/attributes</include>

  <username><xsl:value-of select="$request/username"/></username>

But user name is stored as null in database can any one correct me whts wrong in my approach.
I am adding the crud.xpl of mine
Reagrds,
Smaran

Smaran,

it seems that crud.xpl doesn't use the container authentication data; this may be a bug.

If i understand crud.xpl correctly, the username value is set in line 82 of /src/resources/apps/fr/perssistence/oracle/crud.xpl or line 64 of /src/resources/apps/fr/perssistence/mysql/crud.xpl, respectively. In both cases, the output of /request/headers/header[name = 'orbeon-username']/value is used, assuming that this header field contains the user name.

But the name of the authenticated user isn't availbe in /request/headers/header[name = 'orbeon-username']/value. The path should be /request/remote-user, i assume. AFAIK, "orbeon-username"
appears only in the both crud.xpl files, but nowhere else in the sources. The docs of the request generator don't mention a header field named "orbeon-username" or "orbeon-roles" or "orbeon-datasource":
http://www.orbeon.com/orbeon/doc/processors-generators-request#d30e37

You could try to change crud.xpl manually to use the name of the authenticated user as username; i've attached a patch. Since i don't use SQL persistence, i wasn't able to test i myselft, and i don't know which other effects may be caused by this chance.
