Hi, I developed a Platform Single Sign-On extension and a corresponding extension for my IdP, which is Keycloak based. The code for both projects are here: https://github.com/unioslo/keycloak-psso-extension and https://github.com/unioslo/weblogin-mac-sso-extension I realized that, when using the Secure Enclave as the AuthenticationMethod, and according to Apple's documentation, the Extension doesn’t obtain fresh ID Tokens when they expire if the refresh token is still valid. When using password as the Authentication Method, it fetches new ID tokens when they expire, without prompting the user for credentials, by using the refresh token. My suggestion is that the same behavior should be implemented for Secure Enclave keys. The thing here is that usually, on OIDC flows, the ID/Access tokens are short-lived. It would make sense for the extension to provide fresh ID tokens. It doesn’t seem to make sense for me that, when using passwords, the extension would fetch these tokens, and not when having the Secure Enclave key. By not doing this, Apple almost forces the developer of an extension to fetch new ID tokens themselves, which doens’t make sense when it clearly provides fresh tokens when using passwords. It almost forces the developers to either implement that logic themselves, or to issue longer tokens, which is not so nice. How so you deal with this? Do you simply use the refresh token as an authentication token, or do you do some sort of manual refresh on the extension?

Hi, We developed a Platform SSO extension for our IdP, Keycloak. It would be great to get some feedback on it: https://francisaugusto.com/2025/Platform_single_sign_on_diy/

We have been trying to figure out how to block Apple Private Relay in our enterprise so we can monitor and filter our employees traffic. We are able to block the Private Relay via this process: We used this article from Fortinet to achieve this: https://community.fortinet.com/t5/FortiGate/Technical-Tip-How-to-block-iCloud-Private-Relay-from-bypassing/ta-p/228629 This also appears to block the users ability to utilize Apple iCloud Drive Backups. They would like to allow that still. Is there a way to block iCloud Private Relay while still allowing iCloud Drive Backups to work? I am not finding a document listing the URL requirements for iCloud Drive Backups. We currently have this solution in place: https://community.fortinet.com/t5/FortiGate/Technical-Tip-How-to-allow-iCloud-private-relay/ta-p/383703 Basically this solution is allowing all Apple URL/IPs to go through the firewall and not be filtered. They would like to scan the traffic through. When scanning is enabled the firewall blocks the iCloud Private Relay traffic as it is blocked as being a proxy. Any guidance is greatly appreciated.

The profile expiration date is approaching, and no amount of inquiries will solve it. Create a new profile Download a new profile from Xcode Press archive, press Distribute App, press Enterprise, and distribute Invalid expiration date in profile of summary of review app.ipa content I've tried everything that comes out by Googleing profiles, such as regenerating profiles, erasing caches, updating Xcode, updating macOS, deleting existing profile information, etc. Expiration date different from the expiration date of the profile created in that menu is displayed. The expiration date of the profile I created is December 8, 2026, and the previous certificate is January 22, 2026. However, the profile information of the generated ipa is February 12, 2026. So I can't distribute this app because I'm scared, and the expiration date is coming up. Users should have a period of time to update. Get me a novice developer who's choking up.

I have a question regarding MDM functionality for iOS/iPadOS. Background: According to Apple's support page(https://support.apple.com/en-us/125073), since iOS 26.1, "Previous Wi-Fi configurations will be replaced when a new profile is installed." We have observed that because of this change, when we apply a Wi-Fi configuration profile to an iPad via MDM, the manually configured network settings on the device (specifically, "Configure IPv4" and "Configure DNS") are reset to "Automatic". This erases the manually entered IP address, subnet mask, router, and DNS server addresses. Goal: We want to apply a Wi-Fi configuration profile from our MDM server to connect the device to a specific SSID, while preserving the manual IP and DNS settings that have been configured on the device. Question: Is there a way to prevent the IPv4 and DNS settings from being switched from "Manual" to "Automatic" when applying the configuration profile? For example, is there a specific key-value pair we can add to the profile to either preserve the existing manual settings, or to explicitly define manual/static IP settings within the profile itself for iOS/iPadOS? Reference: Sample Configuration Profile Below is a simplified version of the Wi-Fi configuration profile we are currently using. This profile does not contain any keys for IP address configuration. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>PayloadContent</key> <array> <dict> <key>PayloadType</key> <string>com.apple.wifi.managed</string> <key>PayloadIdentifier</key> <string>com.apple.wifi.managed.13E2E6B3-D4B9-4E23-888A-524B3ED40C38</string> <key>PayloadUUID</key> <string>13E2E6B3-D4B9-4E23-888A-524B3ED40C38</string> <key>PayloadVersion</key> <integer>1</integer> <key>SSID_STR</key> <string>SSID</string> <key>EncryptionType</key> <string>WPA</string> <key>Password</key> <string>Password</string> </dict> </array> <key>PayloadType</key> <string>Configuration</string> </dict> </plist>

Hello Apple Developer Community, I'm experiencing an invalid_client error (HTTP 400) when attempting to authenticate with the Apple School Manager API using OAuth2 with JWT bearer assertion (RFC 7523). Despite verifying all configuration values and following Apple's documentation, I continue to receive this error. Error Details Error: invalid_client HTTP Status: 400 Bad Request Endpoint: https://appleid.apple.com/auth/oauth2/v2/token Response: {"error": "invalid_client"} My Configuration All values have been verified to match Apple School Manager exactly: Organization ID: 55155430 Key ID: 8136a1f6-c995-4010-b964-bc8278c107ef Client ID (Service ID): SCHOOLAPI.7c0c10a0-4d8a-4ef8-a2be-eda040b65c59 Private Key: Loads correctly, signs JWT properly (ES256) JWT Configuration I'm generating a JWT with the following structure: Header: { "alg": "ES256", "kid": "8136a1f6-c995-4010-b964-bc8278c107ef", "typ": "JWT" } Payload: { "iss": "55155430", "sub": "SCHOOLAPI.7c0c10a0-4d8a-4ef8-a2be-eda040b65c59", "aud": "https://appleid.apple.com", "iat": [timestamp], "exp": [timestamp + 30 days] } Token Request Method: POST Content-Type: application/x-www-form-urlencoded Parameters: grant_type: client_credentials client_assertion_type: urn:ietf:params:oauth:client-assertion-type:jwt-bearer client_assertion: [JWT token] scope: https://api.apple.com/auth/schoolmanager What I've Verified ✅ All configuration values match Apple School Manager exactly ✅ Private key file exists and loads correctly ✅ JWT is generated with correct structure (ES256, proper claims) ✅ Key ID in JWT header matches the Key ID from Apple School Manager ✅ Request format matches OAuth2 RFC 7523 specification ✅ Content-Type header is application/x-www-form-urlencoded ✅ Tried both Client ID and Organization ID as sub claim (both fail with same error) ✅ DNS resolution and API connectivity are working ✅ API account appears active in Apple School Manager interface What I've Tried Using Client ID as sub: Tried using SCHOOLAPI.7c0c10a0-4d8a-4ef8-a2be-eda040b65c59 as the sub claim Using Organization ID as sub: Tried using 55155430 as the sub claim (fallback) With and without scope: Tried both including and excluding the scope parameter Different JWT expiration: Tried various expiration times (30 days, 180 days) Verified Service ID format: Confirmed the Client ID follows the SCHOOLAPI.xxxxx-xxxxx-xxxxx format Both attempts (Client ID and Organization ID as sub) return the same invalid_client error. Previous Support Interaction I've contacted Apple Developer Support (Case #102783504559). They confirmed: The technical implementation is correct The issue is an account access/permission problem My Apple Account email is not associated with any memberships The Account Holder must add me to the Enterprise team membership However, I'm posting here to see if anyone in the community has: Experienced similar issues and found a solution Additional technical insights about the invalid_client error Suggestions for what else to verify or try Questions Is there a specific format requirement for the sub claim? Should it be the Client ID (Service ID) or Organization ID? I've tried both. Are there any additional claims required in the JWT beyond iss, sub, aud, iat, exp? Could there be a backend issue with the API account even though it appears active in Apple School Manager? Has anyone successfully resolved an invalid_client error that wasn't related to account access? Is there a delay after creating an API account before it becomes fully active for authentication? Technical Details Language: Python (Flask) JWT Library: PyJWT with cryptography library Algorithm: ES256 (ECDSA P-256) OAuth2 Flow: Client Credentials Grant with JWT Bearer Assertion (RFC 7523) Error Log I've generated a detailed error log showing the exact request/response. The key points: HTTP 400 Bad Request Response: {"error":"invalid_client"} Same error occurs with both Client ID and Organization ID as sub Any Help Appreciated If anyone has encountered this issue or has insights into what might be causing it, I'd greatly appreciate your help. I'm happy to provide additional details or try any suggestions. Thank you! Case Number: 102783504559 API Account: Created in Apple School Manager Status: API account appears active, but authentication fails

We are using an app created with the Apple Developer Enterprise Program within our company. Every year, we recreate and distribute the app in conjunction with the renewal of the provisioning profile. Currently, there are cases where an app that expired in September 2025 is still running, which is causing problems. What could be the cause of this? The app operates on a VPN, but Apple domains are accessible.
