Hi guys I'm with a doubt at dialog plugin I created a user at mariadb server:

---SQL INSTALL PLUGIN three_attempts SONAME 'dialog_examples.so'; CREATE USER test_dialog IDENTIFIED VIA three_attempts USING 'SECRET'; FLUSH PRIVILEGES; ---

now i'm trying to connect as user test_dialog:

the doubts: 1) why it accept my login with password? i *don't* have a password at mysql.user schema

See, you SECRET is in the last column. Password field is MySQL protocol password, from before auth plugin times. When you specify VIA xxx USING yyy the whole 'yyy' string goes into the column mysql.user.auth_string. It cannot go into Password, it might be very long.

2) why i didn't received a dialog like in heidisql?

what do you mean? you should've had a dialog popup in heidisql.

3) there's a auth trace or auth verbose option at client side? or any other command to check if i loaded the dialog plugin?

No, I don't think so. But as you were asked questions ("Password, please"), you can be sure that dialog plugin was loaded. If it weren't, you'd get an error message and wouldn't be able to connect. Regards, Sergei
