Getting the username from a portlet

Question

Hi,
I have a new installation of Portal 10.1.4 and I'm trying to write a portlet that has access to the username from within a JSP. I am trying renderRequest.getRemoteUser() and renderRequest.getUserPrincipal().getName() and both return the username with brackets and a number inside, for example "MCOARR[1]". What I really want is the uid from LDAP.
Looking in the directory server my user is mcoarr (or more specifically, both the uid and cn attributes are set to "mcoarr").
How do I get just the username?
Thanks,
Matt

Yeah, I had to do that too (the text munging stuff). Unfortunately, Oracle Portal doesn't seem to be following the WSRP spec on getting user attributes. There is a whole section in the spec about how to map user attributes in your portlet.xml and then get them in a portlet by doing stuff like:
Map userInfo = (Map) request.getAttribute(PortletRequest.USER_INFO);
String givenName = (userInfo!=null) ? (String) userInfo.get(“user.name.given”) : “”;
String lastName = (userInfo!=null) ? (String) userInfo.get(“user.name.family”) : “”;
This is how it works in uPortal, Liferay and other portals we tried. I don't know why Oracle portal has been through two revs of WSRP support and hasn't got this right yet.
