Username case mismatch

• bug report

What is the current behavior? [REQUIRED]

• If username in DB is lower-case but user used upper case to log-in, the server rejects his first packet due to ticket mismatch.

Steps to reproduce [REQUIRED]

1. Create user with lower-case (eg. helloworld)
2. Login with upper-case (eg. Helloworld)

What is the expected behavior? [REQUIRED]

User should be able to check-in since his packet was valid.

Other informations [OPTIONAL]

We could fix this by lower-casing both usernames in the check here:

DCNC/src/LobbyServer/Network/Handlers/UserInfo.cs

Line 17 in 7821c13

userInfoPacket.Username != packet.Sender.User.Username)

Log

cket 3311448694 vs 3311448694) for invalid user-ticket combination.
