Context: Migrating Zendesk support roles to Genesys Cloud Security Profiles. The “Manage Users” permission is mapped, but SAML SSO fails with 403 Forbidden for these specific accounts in the eu-west-1 region.
Question: Why does this setting trigger an immediate auth rejection instead of a permission denied error? In Zendesk, we just granted the ‘Admin’ tag, but GC seems to require explicit attribute mapping for SSO success.
The best way to fix this is to ensure the SAML assertion explicitly maps the Zendesk admin role to a valid Genesys Cloud Security Profile. The 403 error indicates the identity provider is sending attributes that Genesys Cloud cannot match to an authorized profile, causing the session to terminate before permission checks occur. In load testing, similar mismatches cause connection drops, so precise attribute alignment is critical.
Check your IdP configuration. The role attribute must map to a profile ID or name that exists in your org. Here is the corrected payload structure for the SAML assertion:
{
"attributes": {
"email": "[email protected]",
"role": "Admin",
"gc_profile": "Support Admin"
}
}
Verify the gc_profile value matches the exact name in Genesys Cloud > Admin > Security Profiles. If the mapping is missing, the system rejects the token immediately. This prevents unauthorized access but requires exact configuration on both ends.
This is actually a known issue! While the SAML mapping advice is solid, watch out for the “Manage Users” permission scope. In my experience with weekly schedule publishing, granting broad user management rights often triggers stricter SSO validation checks in Genesys Cloud. The system expects a specific role hierarchy that Zendesk’s flat “Admin” tag doesn’t provide. If you force the mapping, you might get past the 403, but your agents could lose shift swap capabilities or self-service access. This is a real gotcha. Check the role inheritance carefully. The docs on role mapping are a bit sparse, but here is the relevant section: Genesys Cloud Role Mapping Docs. Ensure the IdP sends a distinct attribute for WFM-specific roles, not just a generic admin flag. This prevents silent permission failures later.
