op_response:92 probable soultion for you

[ItchyNitchy]

I've encountered op_response:92 error with Firebird 3.0.5.

Problem was that i have 2 users with identical username on server.

Just want to leave it there cuz i spend tons of time tinkering server configs and error message was not very helpful

Please write down the detailed steps where the error occurs

I used such auth config to reproduce on master branch (with Firebird 3.0):

AuthServer = Srp256,Srp,Legacy_Auth
UserManager = Srp, Legacy_UserManager
WireCrypt = Enabled

1. Create user in Srp:

create user someuser password 'test1' using plugin Srp;

2. Code to reproduce. Login with wrong password:

conn, err := sql.Open("firebirdsql", "someuser:test2@localhost/employee")
err = conn.Ping()
if err != nil {
    panic(err)
}

panic: Error op_response:92

goroutine 1 [running]:
main.main()
        /workspace/go-firebirdsql/master/_examples/test.go:14 +0x5d

Also, if you will try to connect as not existing user you will see crash:

conn, err := sql.Open("firebirdsql", "notexisting:test2@localhost/employee")
err = conn.Ping()

panic: runtime error: slice bounds out of range [:2] with capacity 0
