STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Setup multiple Instances on the same Unix Server and Windows server paths,
except the Ports should be different.
2. First log-in is to one instance as dm user. No issues seen.
Collaborator Workbench opens and Worksheet opens.
3. Second log-in attempt is to a different instance as dm user. "User Already logged in" message is received.
4. Third log-in attempt to this instance but as sop user. The same, "User Already logged in" message is received.

BUSINESS IMPACT
-----------------------
Users cannot log-in 2 Demantra environments in parallel.
