By leveraging the Mac OS X Kerberos service, Outlook for Mac uses the single sign-on mechanism to offer better password handling and a cleaner setup experience. Mac OS X includes built-in support for Microsoft Kerberos authentication and Active Directory authentication policies, such as password changes, expiration and forced password changes, and Active Directory replication and failover. To use this ticketing scheme, both the client and the server must have a trusted connection to the domain Key Distribution Center (KDC). The client can use the same ticket on the network to request other network resources. If an attacker tries to capture and decrypt the information in a ticket, the breach will be limited to the current session. The timestamp included in the ticket indicates that it's a recently generated ticket and is not a replay attack. This decrypted ticket indicates the proof of the client's identity and is used to authenticate the client. If the client successfully decrypts the ticket, it keeps the ticket, which is now shared by the client and the server. The client then attempts to decrypt the ticket by using its password. Then, the authentication server grants the client encrypted tickets that include client information and the session key that expires after a specified period of time. In this scheme, a client must provide a valid user name and password only once to prove their identity to an authentication server. Kerberos protocol uses cryptography to help provide secure mutual authentication for a network connection between a client and a server, or between two servers. For example, MMAC, MCSMA, PCM, RBAR.Outlook 2016 for Mac supports Kerberos protocol as a method of authentication with Microsoft Exchange Server and standalone LDAP accounts. These MAC protocols do not strictly fall into any above category. For example, MACA/PR, RTMAC.Ĭontention-based protocols with scheduling mechanisms –Īll the nodes are treated equally and no node is get deprived of bandwidth. Relative time information is used to achieve effecting reservations.

For example, D-PRMA, CATA, HRMA, SRMA/PA, FPRP. Contention-based protocols with reservation mechanisms –Īll node are kept synchronized. The connection is initiated by the receiver node.

Multiple-channel sender initiated protocols.

The transmission of packets are initiated by the sender node.

Contention-based protocols without reservation/scheduling – It can also use a completely new approach.ġ.Combine multiple features of other protocols.Distributed scheduling is done between nodes.Contention-based protocols with scheduling mechanisms –.Bandwidth is reserved for transmission.Contention-based protocols with reservation mechanisms –.Contention-based protocols without reservation/scheduling –.The primary task of any MAC protocol is to control the access of the nodes to shared medium. MAC protocol is the first protocol layer above the Physical Layer in ad hoc.
