In the case of Guacamole clients that support the "required" instruction, this function will send any of the three unpopulated RDP authentication parameters back to the client so that the connection owner can provide the required information. If the values have been provided in the original connection parameters the user will not be prompted for updated parameters. If the version of Guacamole Client in use by the connection owner does not support the "required" instruction then the connection will fail. This function always returns true.
The client is deemed to be not supporting required when: > return (user->info.protocol_version >= GUAC_PROTOCOL_VERSION_1_3_0); How can you use old protocol? Actually, I see in title you are using guacd 1.5.5 But what is your client? вс, 9 мар. 2025 г. в 16:45, Gal Sabas <gal...@checkpoint.com.invalid>: > I changed the configuration I sent to guacd and now I get the > following error message: > Client does not support the "required" instruction.
