Hello,
unfortunately, we don't have any explicit sso service currently running.
In the past, we simply asked the container (tomcat) to manage
authentication of users for all our webapplication and we followed tomcat
directions on how to share principal for all applications (
http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html#Single_Sign_On_Va…).
This works well when all application use container authentication and the
only client is the user's web browser. Unfortunately, things will change as
we will base our intranet on xwiki instead of having separate spread
applications the user needs to connect to. This mean the web server (now
jboss) will be the http client of all other services, and thus realm based
sso won't work. For some of those service we use generic technical account,
so no problem, we just store the password. But for some other, we must
transmit the user / password of current xwiki user so xwiki is seen by this
service as this user.
And none of those behind the scene applications were ever configured to
use kerberos or anything alike. Moreover, i would like to avoid the
nightmare of maintaining such a service when simply forwaring user / pass
to next service would solve my problems :)
Storing plain-text user password is never a good idea, be it on the
database, filesystem or in memory.
If you store passwords in the session, some XWiki applications could read
them, someone in your organization with programming access level can access
them, a hacker that escalate to have access to the machine or to
programming rights in the application can read them, etc.

Hi David,
which SSO service dou you use internally? XWiki authenticators already
exist for CAS, Kerberos and NTLM, maybe you could draw inspiration from
them.

Hello,
I was hoping that somehow, when submitted via the form, password gets
recorded until the end of the session. We can't afford, for the sake of
user experience, to ask password every time user need to access a hidden
system he is not even supposed to know is separate from the wiki. That's
why we are writing some macro / components so that it's xwiki that access
those system for him. This include various webservices, a documents
storage
and so on. We try to keep a single sign on
policy. Of course, i don't
want
user password stored anywhere on disks, but
keeping it in user session
seems a good trade-of for me.
I plan thus to create my onw xwikiauthservice that delegates to ldap
service and store this in user session.

Hi,
Fortunately, you can't. You can only access/verify a hashed version of
the password.
Note that asking for a password again is not necessarily a bad UX,
especially if it is to allow access to a sensitive area/operation.
Cheers,
Jerome.

Hello,
i am writing a component that need a password. Because this password
will be the
same for current user as the one he used to log-in, it would
make for crappy interface ot ask it again to user. So i need to know how component or a groovy script can access the
username / password of
current
logged-in user.
