        <remarks>On Unix systems, the role is mapped to Unix groups.   For users to be considered to have a certain role, the role must be listed in the Unix groups (the /etc/group file) and it must contain a list of users that belong to that group.

<para>
For example, if you want to check that the user is in role "USAGNT\\UGR_RBP" the file /etc/group should contain a line like this:
</para><example><code lang="/etc/group">
USAGNT\UGR_RBP:x:300:miguel,don,jon,julia
  </code></example><para>
In this particular example, the users miguel, don, jon and julia belong to the "USAGNT\UGR_RBP" role.
