Description
This plugin allows to not only have one server password specified by sv_password, but to have several passwords each giving different access permissions.

Requirements
This requires the Connect extension (only the Source 2009 engine is supported).
Thanks to asherkin for this.

Configuration
This plugin uses a modular approach for its configuration backend. At this time there is only a keyvalues-password store implemented.
There are three options that can be set for each password: A group to assign to the player, an immunity value and a flag string. If you don't specify any of those, but just the password it will allow you to get on the server like the original sv_password one.
After changing one of the stores, you can reload (and reapply) the passwords by using the command: sm_reloadpasswords.

Using KeyValues
This is pretty much the same as you already know from the core admin system.
Configure passwords by editing addons\sourcemod\configs\admin_passwords.cfg.

"Passwords"
{
	"1234"
	{
		"groups"	"Administrator"
		"flags"		"z"
		"immunity"	"99"
	}
}

Players connecting using the password '1234' would be added to the group 'Administrator', be given the 'z' flag and an immunity value of 99.

Writing your own stores

Public Servers:
You don't have to set the sv_password convar for this, but then your players need to connect via console to get their permissions:

connect <ip>:<port>;password <password>

Bugs
Report any you find, this is not as well tested as I would have liked it to.

whyyyyyyyyyyy

thanks
i've never intended it to be used as Kleiner suggested, furthermore i don't get how it's especially useful for those servers.

Oh my god, this plugin, as well as your other plugins, is so useful.
