All users belonging to that site can log in with their username and password.

If there are no users you can log in like this:

Username: admin
Password: stats

Activate the option SSL on the tab Basic of the web and go to the tab SSL. Provide your information there (State/county and Organizational unit are optional").

Please leave empty the fields SSL Request and SSL Certificate. Choose Create Certificate under Action and then click on Save.

Afterwards, if you go to the tab SSL again, you will find the Certificate Signing Request (CSR) under SSL Request. Copy the CSR. With this CSR you can apply for an SSL certificate at companies like Verisign (www.verisign.com), Baltimore (www.baltimore.com), Entrust (www.entrust.com), Geotrust (www.geotrust.com), IPSCA (www.ipsca.com) or InstantSSL (www.instantssl.com).

If you want to add something manually to other files, e.g Postfix' local-host-names, you can put your configuration at the end of the file in a section that is not overwritten by ISPConfig.

Go to Management -> System Config -> Settings. On the tab ISP-Manager you will see the field User Prefix where you can specify a prefix for users. You can use one of the following placeholders:

[DOMAIN]

[HOST]

[WEBID]

If you don't want a prefix, just leave it blank.

Please check that you did not mix up customers and users. A customer can login to the ISPConfig and manage his sites (and create system users on the tab User & Email) but he cannot login to the system (e.g. by using FTP, email) because he is not a system user. A customer is an object that exists only in the ISPConfig, but not on the system.

A system user cannot login to the ISPConfig, but he can use services such as email, etc.
