Hello everyone, I encountered an unexpected issue. Apache Guacamole 1.5.5 is installed. Authentication is done via LDAP, followed by two-factor authentication using TOTP. The problem occurs at the two-factor authentication stage when the QR code and the associated secret key information are displayed. At the end of the secret key, ==== is appended. On Android devices, Google Authenticator and other apps work fine—both when scanning the QR code and when manually entering the key. However, on Apple devices, the same Google Authenticator throws an error when scanning the QR code, and when entering the key manually, it generates completely incorrect codes for login. The only modification made to the guacamole.properties file was adding totp-mode sha256. After discovering the issue, I tested all available encryption methods and digit lengths, as well as regenerated the TOTP secret completely, but nothing changed. Has anyone encountered this issue before?
Kind regards Roman
