It was brought to my attention that if account is waiting for confirmation (and due to that authentication is failing), currently Tigase reports back temporary-auth-failure error. This error suggest that without any user interaction, account may become accessible as the "issue" is only temporary.

For blocked accounts, Tigase returns account-disabled error that notifies user that account is blocked and it needs to take action to actually "fix" account state.

Due to the nature of the error (account pending confirmation), we should be returning account-disabled to let user know that some action has to be taken to enable his account.
