Each User will have several ways to log on from this page.
If the Encrypted login checkbox is checked, the authentication against the server is done by a SHA1 algorithm.
The SSL Mode link will take the user to the same page but via https instead of http. i.e. the communication is encoded by SSL and the SSL port from the Administrator Settings will be used. Of course, the link is not shown if the user has already accessed the Login page via https.
User can use Forgot your password link to show a special dialog where they can fill in their account and their password will be sent to both specified account and their alternative email address (See Settings -> Accounts -> Modify). This feature can be disabled in Administrator Settings.
This will send your password to your account itself since you might have its password save in your email client and IF you have an alternate email configured in webmail options/modify account, it will send the password to that account also.
The Sign-up for a new account link is there only in case the Allow sign-up process option in the Administrator Settings is enabled. It allows users to create new accounts without any effort from the Administrator of server. It will take the user to a new dialog:
All the fields except the Name have to be filled properly. The Word verification feature restricts spammers and other unwelcome "users" from creating accounts automatically with robots.
The SMTP service has to be started, otherwise the image will not be generated. The Administrator of the server may also change the font and size of the generated letters in Merak\Spam\spam.dat file using the SpamChallengeFont and SpamChallengeFontSize parameters.
If the Complete Merak mail server integration option in Administrator Settings is enabled, the account is created under the primary domain with the same default settings as the account created via Merak Config.
The Administrator can change the default settings for account creation.
The last feature on the Login page is Fast Login.
If user fills in their username and password in the dialog, they are saved by his/her browser and next time he/she clicks on this link he/she is logged on automatically. It is valid until user closes their browser.
This option is not recommended because of security issues involved.
