Hello,

We have not tried to use 1.0.3 but this shouldn't be a problem. You will need to follow the instructions at https://github.com/FuseCP/SolidCP/tree/master/SolidCP/Sources/Tools/Guacamole/SolidCPAuthenticationProvider on installing the provider.

If you have any issues please feel free to let us know here or file a issue on github.

Regards,

Trevor
