"The version of Sun Java System Identity Manager running on the remote
host has the following account enumeration vulnerabilities :

- The error message for a failed login attempt is different,
  depending on whether or not a valid username was given.

- Requesting IDMROOT/questionLogin.jsp?accountId=USERNAME results in
  different results, depending on whether USERNAME is valid.

A remote attacker could use these to enumerate valid usernames,
which could be used to mount further attacks.

There are also other issues known to be associated with this version
of Identity Manager that Nessus has not tested for. Refer to Sun
Security Alert #253267 for more information.");
