I made a nice plugin to initiate a server maintenance, you can change the server to allow admins to enter only.

Installation:
Download the plugin using the button below [Get Plugin], then drag it to addons/sourcemod/plugins to install it.
Then reload the server/change map/"sm plugins load maintenance" in rcon.

Update:
Same as installation just you can't change map for that, and reload instead of load.

Console variables:

sm_maintenance_enabled - Is the plugin enabled? [1] sm_maintenance_version - Plugin's version. sm_maintenance_kick_reason - Kick reason, {name} - The player's name. (Don't add a dot in the end of the sentence) [Hey there {name}, this server is under maintenance and admins are allowed to join only]

Changelog:

1.4 - Fixed the bug in L4D2. 1.3 - Fixed a bug that you see %N instead of player name in kick. 1.2 - Added some suggestions by Dr McKay, added "Kick reason" CVar, fixed a bug which only admins were unable to connect while a maintenance. 1.1 - Added some suggestions that Impact123 and TnTSCS suggested, added change-log. 1.0 - Initial release.

But then admins can give the password to their friends..

[Impact123]

if(GetUserAdmin(client) == INVALID_ADMIN_ID && gH_Enabled)

Goes to

if(gH_Enabled && GetUserAdmin(client) == INVALID_ADMIN_ID)

Pretending that this is a script that will be active 0.5% a day your script still checks every joining client for their flags, sense?
Also you should either overthink your convarchecking method or add an convarhook.
Also i would suggest you use the CheckCommandAccess function.

Here's an ultra cramped version, just for fun (with a few suggestions, like mentioned above):

Spoiler

PHP Code:

#include <sourcemod>
#pragma semicolon 1
new Handle:gH_Enabled = INVALID_HANDLE; new bool:enabled = false;
#define PLUGIN_VERSION "1.0"
public Plugin:myinfo = { name = "Server maintenance", description = "Allows to initiate a server maintenance to allow admins to join only.", author = "TimeBomb", version = "1.0", url = "http://vgames.co.il/" }
public OnPluginStart() { CreateConVar("sm_maintenance_version", PLUGIN_VERSION, "\"Server maintenance\"'s version.", FCVAR_NOTIFY|FCVAR_DONTRECORD|FCVAR_PLUGIN|FCVAR_REPLICATED); gH_Enabled = CreateConVar("sm_maintenance_enabled", "0", "\"Server maintenance\" is enabled?", FCVAR_PLUGIN|FCVAR_REPLICATED, true, 0.0, true, 1.0); HookConVarChange(gH_Enabled, OnEnabledChanged); AutoExecConfig(); }
public OnClientAuthorized(client, const String:auth[]) if (enabled && !CheckCommandAccess(client, "allow_when_maintenance_mode", ADMFLAG_GENERIC)) KickClient(client, "Hey there %N, this server is under maintenance and admins are allowed to join only.", client);
public OnEnabledChanged(Handle:cvar, const String:oldVal[], const String:newVal[]) { enabled = GetConVarBool(cvar); }

Forum bug, from the sourcemod.net compiler it does, but from the thread it isn't.
