[patch][6519] Mangos-realmd: Some Usernames Can't Login

Recommended Posts

Revision: 6480

Description of bug:

Some usernames can't login to mangos-realmd, even if they put correct password.

Example of such username is "kreved"

How to repeat:

1) run mangos-world

2) type "create kreved somepassword somepassword"

3) run mangos-realmd

4) Run client and try to login

Other information:

This bug activates when sha1(username) ends with 0x00

(For example sha1("KREVED") = 901b43e4f42ce49ba47b112ab70f6f554e9c4400)

this 0x00 is lost when "t4.SetBinary(sha.GetDigest(), 20);"
