[dev] Auth driver : validateAuth false and imp still try to login to Imap

[SSRI]

Hi,

We use a custom authentication backend and have implemented a  
validateAuth() function.

When validateAuth() returns false, we have noticed that imp still try  
to login to our IMAP server 3 times before user is logged out.

Why user isn't disconnected immediatly after the first time  
validateAuth() returns false ?

Regards.
