Can't PAM authenticate as user rstudio-server

I am running Ubuntu 11 in a guest OS using VirtualBox.

When I try and log in to RStudio Server using the account that I set up when I installed Ubuntu, I am able to log in but after a short wait I get the error "Unable to connect to service".

To try another user account, I used adduser to create a user "rweb". But now I am not even able to login as that user. I have downloaded and built pamtester. When I su to rstudio-server and run

pamtester rstudio-server rweb authenticate

I get "Authentication failed". The auth.log looks like this:

Jun 26 14:28:24 seshat-ubuntu-rstudio unix_chkpwd[11250]: check pass; user unknown
Jun 26 14:28:24 seshat-ubuntu-rstudio unix_chkpwd[11250]: password check failed for user (rweb)

I am able to su normally between these accounts so I know that the users exist and the passwords are right.

    Kevin,

    Can you do cat /var/log/user.log and see if there are any RStudio related messages in there (they'd be prefixed with either rserver or rsession).

    Might shine some light onto what is going wrong.

    I don't have a /var/log/user.log file. Any idea how I can enable it?

    Hi Kevin,

    Actually if pamtester fails for you, then the /var/log/user.log won't help us at this time.

    Have you done any customizations to your /etc/pam.d directory, or is it all stock Ubuntu 11.04?

    I haven't done any customizations. I tried the suggestion of creating an
    /etc/pam.d/rstudio but when that didn't work I deleted it.

    Two things I could mention:

    1) I can authenticate using pamtester if I'm the root user, but not if I'm
    rstudio-server
    2) Because I am running in a VM I got a message when I started Ubuntu that I
    can't run the latest & greatest UI platform (I forget what it's called; I
    normally use Centos). So I maybe running a little bit different UI
    environment than most Ubuntu users.
