Symantec Encryption Management Server (SEMS) provides a feature called Symantec Web Email Protection, formerly known as Web Messenger that allows a user to login to a secure inbox via https to receive secured email from a sender. No keys are required, as the data is secured over the https session.
Part of the designed behavior, which is a security feature of Symantec Web Email Protection, is that a user may be logged into their account using only one web session. In other words, it is not possible to have multiple/consecutive logins to the secure inbox and attempting to do so will result in the following message presented to the user:
PGP Universal Server:
"A Web Messenger session has already been opened for this account from the address: 10.1.1.10. Please log out of the other session and try again"
Symantec Encryption Management Server:
"A Web Email Protection session has already been opened for this account from the address: 10.1.1.10. Please log out of the other session and try again"
This is a security feature and is working as designed.
It is possible to disable this security feature, which is not generally recommended as it ensures the Symantec Web Email Protection user is the only user logged into the account at that time.
If disabling this security feature is needed, please contact Symantec Technical Support for assistance to make the changes via SSH.
