Logged in users on a Linux server are counted twice
Scenario:
1. Log into a linux server interface as root.
2. Inititiate an SSH session with the server using Putty and a valid user account (e.g. fakeuser).
3. Log into TTY2 of the linux server interface using another valid user account (e.g. faketester).
Issue:
With these three login sessions, the linux server reports that there are five (5) users logged into the server and lists the users as:
faketester
fakeuser
fakeuser
faketester
root
The TTY2 and SSH sessions are counted twice.
I am testing this on a RHEL6.5

DESCRIPTION
The cdsclerk command manages the interface between clients and the CDS server.

diagnostic work on the host system.
EXAMPLE
Before you run the following process, make sure that other clerks are not running. To start the cdsclerk process, follow these steps:
Make sure that a CDS server is already running somewhere within the cell. Log in to the system as superuser (root). Log in to DCE as the
machine principal of the local host. Enter the principal name in the format /hosts/hostname/self as shown in the following example command
for a host named orion whose password is smith: # dce_login hosts/orion/self smith Enter the following command to see if the dced process
is already running: # ps
If the dced process appears on the list of active processes, proceed to step 5. If the dced process does not appear on the list of active
processes, enter the following command to start the process: # dced Enter the following command to start the cdsadv process: # cdsadv Enter
the following command with the appropriate arguments to start the cdsclerk process: # cdsclerk
