SessionState SQLServer error

[Hongki Kim]

Hi,

We are on Vault 7.2.1 Standard.

Vault Web Services SessionState was changed to use SQL Server Session State.
web.config settings:
<sessionState mode="SQLServer" allowCustomSqlDatabase="True" sqlConnectionString="Server=xxxx; Database=xxxx; UID=xxxx; PWD=xxxx" cookieless="false" timeout="10080" />

However, the following error occurred during the login to the Vault Client and Admin console.
Error message:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

SQL Server Session State is not currently supported by Vault. I can enter a feature request for the developers to review for some future release if you would like.
