Smart Arena supports single sign-on through your organization’s identity provider, such as Microsoft Entra ID (Azure AD) or Active Directory Federation Services (ADFS).
When you sign in using SSO, your organization’s identity provider verifies your identity. Smart Arena can grant access only after the authentication process has been completed successfully.
Who is responsible for resolving the issue?
If the login fails before the Smart Arena interface appears—for example, on a Microsoft login page, your organization’s ADFS page, or in a Windows sign-in dialog—the issue is usually related to your organization’s SSO configuration, permissions, or user account.
These issues must be reviewed by your internal IT team or SSO administrator. Smart Arena does not have access to your Microsoft Entra ID, Active Directory, or ADFS environment and cannot change its configuration.
How to identify an issue with your organization’s SSO?
The issue is most likely related to your organization’s identity provider if:
The error appears on
login.microsoftonline.comor your organization’s ADFS domain, rather than on a Smart Arena page.The message includes a Microsoft error code beginning with
AADSTS.A Windows dialog appears with a message such as “Sign in to access this site.”
The user never reaches the Smart Arena interface.
Common Microsoft Entra ID / Azure AD issues
1) The user is not assigned to the application
An error such as
AADSTS50105usually means that the user has not been assigned access to Smart Arena.Your administrator should open: Enterprise applications → esmartarena → Users and groups
The administrator can then assign the individual user or an appropriate user group to the application.
2) Conditional Access, MFA, or access restrictions
A Conditional Access policy, multi-factor authentication requirement, or another security rule may be preventing the user from signing in.
Your Microsoft Entra administrator should review the relevant Conditional Access and MFA policies for the affected user.
3) Disabled account, expired password, or incorrect group membership
The user’s account may be disabled, their password may have expired, or they may not belong to the required Active Directory group.
Your administrator should review and update the account in Microsoft Entra ID or Active Directory.
Common ADFS issues
1) Windows sign-in dialog or blank page
This can occur when:
The user is not connected to the corporate network.
A VPN connection is required but is not active.
The browser is not configured for Windows Integrated Authentication (WIA).
The user does not have permission to access the Smart Arena application in ADFS.
Your ADFS administrator should review the user’s access permissions, network connection, VPN requirements, and browser configuration.
2) Certificate error or expired ADFS certificate
An expired or invalid ADFS certificate can prevent users from signing in.
Your ADFS administrator must renew or replace the affected certificate.
The user is not in the required Active Directory group
The user may need to be added to a specific Active Directory group before access can be granted.
Your Active Directory administrator should verify the required group membership.
What to check before contacting Smart Arena Support
Before opening a support request, please complete the following steps:

Record the complete error message and any displayed
AADSTScode.Record the Request ID and Correlation ID, if available.
Ask your SSO administrator to review the relevant configuration and permissions described above.
