The user login on the estos UCServer requires authentification. This can be done either via a UC password or via a Windows® application. The combination of user database and user login configuration dictates the process used. The technical background is described in the following.
Active Directory® user administration, domain authentification
The user names come from the Active Directory®. Only users who are configured in Active Directory® can log on. The users will be authenticated at the Active Directory® implicitly or explicitly with their Windows® login with NTLM. The estos UCServer does not have to be member of the domain, the authentication at the Active Directory® takes place using LDAP. The password of the user will never be transmitted via the network.
Integrated user administration, UC password
The user names come from the integrated user database. Only users who are configured in the estos UCServer can log on. The UC password is specially configured for the user and stored in the user database. The user's UC password is transmitted over the network in encrypted form.
Integrated user administration, domain authentification
The user names come from the integrated user database. Only users who are configured in the estos UCServer can log on. The users are authenticated either implicitly or explicitly via NTLM directly on the estos UCServer. The user's password is not transmitted over the network under any circumstances.
