With this function you can find an administrator through SteamId, for example...

PHP Code:

#include <sourcemod>

public Plugin myinfo =
{
    name = "Check Admin",
    author = "sekm",
    description = "",
    version = "1.0",
    url = "https://steamcommunity.com/id/h5r/"
};

public void OnPluginStart()
{
    RegConsoleCmd("sm_checkadmin", Command_CheckAdmin);
}

public Action Command_CheckAdmin(int iClient, int iArgs)
{
    AdminId iAdmin = FindAdminByIdentity("steam", "STEAM_0:0:1347337");

    if (iAdmin != INVALID_ADMIN_ID)
    {
         PrintToChatAll("SteamId: STEAM_0:0:1347337 has admin");
    }
    else
    {
         PrintToChatAll("SteamId: STEAM_0:0:1347337 has not a admin");
    }
}
