We had a talk and he tested some stuff on me.

Looks like it ain't working. The only servers who have been able to successfully ban me was Team Cream servers.

That was long ago, though.

Edit: I tested on them again. They were able to ban me.

Ok so this also works on skial

When I trigger an SMAC ban on myself, the sourcebans page shows

STEAM_ID_STOP_IGNORING_RETVALS

STEAM_0:0:0

76561197960265728 <---- profile link, but it leads to nothing





Oh, and I can still join their other servers. I believe after a while I can join the one I was banned from.

Admins also try to manually ban me from the server via the Sourcebans page, but it doesn't do crap because I have no steamid in the server!

This hack of a method has been fixed and optimized, integrated into an auto-updating central plugin:

The weird thing is, and I guess this is expected behavior, but Connect can get the SteamIDs just fine. I guess now we just need to figure out a way to force it on a client or something, iunno. An extension or native that would force IDs would fix a bunch of other problems too.

If
Code:
GetClientAuthId(client, AuthId_Steam2, auth, sizeof(auth)
returns FALSE, then
Code:
IsAuthorized(client);
should return FALSE too according to my experiments in the past, though that was with CS:S.

If GetClientAuthId returns FALSE, and you're still using the contents of "auth", that is when when you're getting "STEAM_ID_STOP_IGNORING_RETVALS", it should not be returning TRUE at the same time as providing "STEAM_ID_STOP_IGNORING_RETVALS".

Even the very old GetClientAuthString, says the same as the newer GetClientAuthId:

Code:
Return:
True on success, false otherwise.
&&

Code:
Return Value

True on success, false otherwise.

Many years ago, I started out with some plugins here from AM, then I changed to my own plugins, and/or re-built them to suit my needs better.

Many of them was using like the above example I made in POST #5.

I ended up on having a lot of issues, sometimes with empty or invalid Steam ID's, and when I finally saw the documentaiton, I found that the plugins wasn't doing things according to the API (checking TRUE vs FALSE return value)

I then changed things from:

Code:
GetClientAuthString(client, SteamID, sizeof(SteamID));
PrintToChat(client, "Your Steam ID is: %s", SteamID);
to

Code:
new bool:bSteam32 = GetClientAuthString(client, SteamID, sizeof(SteamID));
if (bSteam32) {
  /* Do whatever I wanted to do with SteamID here */
  PrintToChat(client, "Your Steam ID is: %s", SteamID);
} else {
  LogError("Something failed here ... bla bla bla");
  PrintToChat(client, "Something went wrong when looking up your Steam ID, sorry.");
}
Since then, there was NEVER any problems retrieving the correct Steam ID any more on those third party plugins after they were re-built this way.

I don't intend to be rude, but for plugin creators, the thing is very simple - make sure to follow the documentation 100%. That worked for me when creating my plugins, as well as when fixing broken plugins created by others.

For the above "temp fix", I would rather suggest kicking people, like SMAC does, if the player hasn't validated within like 15, 30, 45 or 60 seconds - depending on what you prefer. 15 seconds should usually be enough, unless the Steam network is down.

OnClientPostAdminCheck will never be called, if Steam network is down (or STEAM_ID_PENDING / STEAM_ID_STOP_IGNORING_RETVALS), and therefore I usually suggest using that one for "on-connect" things when you need to know who they really are.

Makes sense. Just did a bit of checking with below:

and it seemed to reach 3 consecutively. Do you know if downned Steam servers might trip up GetClientAuthId? If it does, then would kicking also false-positive?

Go for it. It's been live and worked for me all last night. I just am really unsure about false-positives if Steam servers are down.
