Ghidra Auth

Setup

Compile / download the ghidra auth binary. Edit the following lines in server.conf

wrapper.app.parameter.1=-a4
wrapper.app.parameter.2=-jaas ./jaas.conf
wrapper.app.parameter.3=-u

Then modify jaas.conf

auth {
	ghidra.server.security.loginmodule.ExternalProgramLoginModule REQUIRED
		PROGRAM="/path/to/ghidraAuth"
		TIMEOUT="10000"
		ARG_00="/path/to/ghidra/server/"
		ARG_01="/path/to/ghidra/repositories/~admin/"
		ARG_02="default_repository_name" // default repository
		ARG_03="https://example.com/auth"
	;
};

Note: it sends a json document with username and password fields as a post request to the API. If the response is ok the user will be authorized. It's beyond the scope of this to actually handle that part, maybe in the future :3
