Issue

The following error occurs when the user tries to login into PME Web:
User is not licensed

• The problem happened even when no other user was logged in PME Web.

• By default PME comes with 2 web licenses, included in Base License (applies to both PME 9.0 and above versions upto PME2023). In this case 2 additional web licenses were purchased, for a total of 4 licenses.

Resolution

Database Warning: “This article contains information about editing the database. Please note, editing or updating anything in DB may cause permanent damage and result in PME to function improperly. This procedure should only be performed by users familiar with SQL Server Management Studio. Kindly take a backup of the database before performing any such action."

Licenses are assigned to users. In case there were previous users, the assigned license needs to be freed.

In order to achieve this run the following script:

delete FROM [ION_Network].[dbo].[GroupMembershipMap]

where TrusteeID NOT IN (SELECT UserID FROM [ION_Network].[dbo].[Users])

For convenience the script is attached to this article.
