Dynamics 365 version 9 on premise session timeout and user prompted to re-authenticate after 30 minutes

(0) ShareShare
ReportReport
Posted on by CRMDevPL 40

Firstly, there is NO user interface for configuring Session Timeout at Settings > Administration > System Settings > General Tab.

The problem is that users are prompted to re-authenticate approximately every 30 minutes.  I have detailed the environment below. Any help would be greatly appreciated.

Steps to Reproduce:
Open a browser (chrome or ie11) > navigate to mycrm.yadadada..com/.../main.aspx
Minimize the browser or continue working
Wait ~30 minutes
Maximize the browser
You will be prompted with this dialog: "Your Microsoft Dynamics 365 session is about to expire. To continue working, please sign in again." with a SignIn button and a Cancel button
If user clicks Sign In, browser navigates to mycrm.yadadada.com/.../dlg_reauthenticate_success.aspx
If user clicks Cancel, browser navigates to ourSTSServer.yadadada.com/.../

Environment: New Dynamics 365 version 9 single server environment, then applied service packs to 9.0.8.9. Server is configured for Claims-Based Authentication. The server was mistakenly configured for IFD, which was subsequently removed/disabled.  Our environment uses a Security Token Server.

IIS 10 - default settings configured by CRM installation except for CRMAppPool > Advanced > Process Model > Idle Time-out (minutes) (we changed from 1500 to 0).

The entries below appear in the IIS log at the time the re-authenticate dialog appears:

These are the relevant settings from MSCRM and BaseOrg databases:

MSCRM_CONFIG.AllowCustomInactivityDuration = 0 and AllowCustomSessionDuration = 0

MSCRM_BaseOrg
SessionTimeoutEnabled = 0,
SessionTimeoutInMins = null,
SessionTimeoutReminderInMins = null,
InactivityTimeoutEnabled=0,
InactivityTimeoutInMins=null,
InactivityTimeoutReminderInMins=null

    This was resolved by having the ADFS team review the 2 parts of the ADFS configuration:

    Global SSOLifetime to 600

    and

    Set-ADFSRelyingPartyTrust -Targetname "relying_party" -TokenLifetime 600
