Background
Meridian client applications use PDFTron technology to show PDF files. The technology sends server-generated intermediate XOD files to the clients for viewing but first, their access to the files must be authenticated.
Description
In environments where Active Directory users have too many security group memberships assigned, authentication attempts can exceed the maximum authentication token size (also called token bloat). When that happens, this error can occur and PDFTron may fail to display the files.
Microsoft provides a PowerShell script to check for users that might be affected by this issue so that you can reduce the number of security groups assigned to them or increase the size of the authentication token as described in MaxTokenSize and Windows 8 and Windows Server 2012.
Even if MaxTokenSize is increased, PDFTron might require a new configuration file to function with the new size. The pdftron.js configuration file might need to be updated on the Meridian web server (default path: C:\inetpub\AMM\Src). Contact Accruent Technical Support to confirm that you will benefit from this fix and to obtain the file.
