Integrate AD or OpenLDAP with SafeSquid

Network enterprises that have a large number of users, popularly manage user credentials via a centralized system. The centralized system ensures user identification across all the networked enterprise resources and services. Users too benefit immensely, as they need a singular credential to access anything across the network enterprise.You can organize all users into groups based on IP addresses, user names or security group memberships in Microsoft Active Directory. Every group gets its own filtering exceptions and blocking rules. Authenticate your domain users using Kerberos, NTLM or Basic LDAP.

Create User Groups based on network IP and LDAP (Active directory)

Setup your users into different User Groups. You can then set restriction policies for specifically these User Groups in the Access Profiles section.

Integrate a Linux Host with a Windows AD for Kerberos SSO authentication

Kerberos Authentication support is particularly useful for Enterprise networks that have a Microsoft AD based Domain controller. By properly configuring the necessary Kerberos related factors, your enterprise Internet users can optionally enjoy Windows Integrated Authentication. Windows Integrated Authentication is a non-interactive authentication process, that uses SSO authentication. SSO ensures that your users do not have to manually provide their user credentials as username / password to access your networked enterprise resources and services, yet their access is restricted as specified. SSO, thus not only just adds convenience to the overall user experience, but also enhances security.

Adding Users using SafeSquid for Basic Authentication

If you don't have LDAP server to integrate with SafeSquid, but you want authenticate users by assigning usernames and passwords to your users.

Bypass Authentication

Caching Specific websites

Content Caching improves bandwidth efficiency. A page or file, when requested by a user, is served to the user and a copy of it is also maintained locally in the cache. So, when a request is made to fetch the same page or file, it is served with the local copy, instead of 'a fresh fetch'. SafeSquid has a very neat, efficient and manageable Content Caching system.
