Dynamic Directory Lecture 3

Slide 2

Active Directory Definitions AD is Microsoft\'s combination of the significant undertaking wide index benefits inside a solitary, replicable information store and managerial interface AD is a system based question store and administration that finds and oversees assets, and makes these assets accessible to approved clients and gatherings. The 2 segments of AD are the Data Store and the AD Services that follow up on that information

Slide 3

AD Advantages Provides concentrated logon and validation indicate for clients get to assets A point of convergence for brought together organization and administration A searchable store for data about each system question and its characteristics Standard-based structures and interfaces take into account item interoperability and similarity with 3 rd party items Scalable (essentially no restriction on number of articles)

Slide 4

New Features Restart ability Read-just Domain Controller Auditing changes Multiple Password/Account Lockout Policies in a Domain AD Lightweight Directory Services Role

Slide 5

DNS is an Internet standard administration that interprets effortlessly lucid host names, for example, mycomputer.microsoft.com , to numeric IP addresses. Space names for DNS depend on the various leveled naming structure (rearranged tree structure): a solitary root area, underneath which can be parent and kid areas (branches and clears out). Every PC in a DNS area is exceptionally recognized by its DNS completely qualified space name (FQDN), e.g. server1.ifsm.umbc.edu Dynamic DNS – fresher standard, required for AD

Slide 6

AD and DNS incorporation Active Directory and DNS have the same progressive structure. All AD names take after DNS traditions DNS records (zones) can be put away in Active Directory. Dynamic Directory customers utilize DNS to find space controllers.

Slide 7

AD Organization A hidden standard of the AD is that everything is considered and protest – individuals, servers, workstations, printers, and so on. Each protest likewise has certain characteristics Object classes are meanings of the question sorts that can be made in the AD.

Slide 8

Controlling Object Access Every question has an ACL that contains data about who has admittance to it and what they can do with it. Controlling access to the question in AD is not the same as access to the protest itself. Advertisement authorizations just determine whether a client, gathering or PC can see or adjust a protest\'s properties in AD. Get to can be setup for individual protest properties

Slide 9

Schema An arrangement of question definitions (question classes) and their related qualities Provides information on what questions and ascribes are accessible to the Directory Allows overseers to change and include new question classes, protests and characteristics as required, making the diagram extensible Because of this adaptability, AD is equipped for being the single purpose of organization for every single distributed asset (records, fringe gadgets, have associations, databases, Web get to, clients)

Slide 10

AD Organization AD protests are sorted out around a various leveled area display that permits versatility and expandability Domain demonstrate building pieces are: - areas - area trees - backwoods - association units

Slide 11

Name Space AD depends on the idea of a namespace, that is a name is utilized to determine the area of a question AD space names compare to DNS area names Each protest has distinctive approaches to allude to it, and each name pinpoints the area of question in AD

Slide 12

Domain Logical segment involved clients, PCs and system assets that share a typical consistent security limit and use a typical namespace (e.g. ifsm.umbc.edu) Domains can be masterminded into a various leveled parent-youngster structure All spaces keep up their own particular security strategies and security associations with different areas Requires no less than 1 Domain Controller (where AD database is put away) If more than 1 DC (prescribed) – they utilize multi-ace replication

Slide 13

Trusts Logical associations between areas to permit clients from one space to get to assets in another area Can be maybe a couple way Can be transitive, intransitive or unequivocal Trust wording: Trusting trusts Trusted Domain Trusted Domain (Users) Trusting Domain (Resources)

Slide 14

Transitive Trusts Domain B A transitive trust is a trust between two spaces in a similar area tree/woodland that can reach out past these two areas to other trusted areas inside a similar space tree/backwoods. A transitive trust is dependably a 2-way trust - both of.the spaces believe each other. As a matter of course, all Windows Server 2008 trusts inside a space tree/backwoods are transitive trusts. Space A Domain C

Slide 15

Domain Tree Consists of pecking order of areas sharing a typical mapping, security trust relationship, and a Global Catalog Formed through the extension of tyke areas, and there\'s one root space (the initially made area) Defined by a typical and coterminous namespace

Slide 16

Domain Tree Example Toysrus.com Marketing.toysrus.com Sales.toysrus.com ny.marketing.toysrus.com

Slide 17

Domain Forests Domain trees with various namespaces associated by trust connections All trees inside the woodland share a Global Catalog, setup and blueprint. Basically a reference point amongst trees and doesn\'t have its own particular name.

Slide 18

Domain Forest Example toysrus.com Babiesrus.com Sales.toysrus.com Marketing.toysrus.com Sales.babiesrus.com HR.Babiesrus.com Ny.marketing.toysrus.com Ny.sales.babiesrus.com

Slide 19

Organizational Unit Administrative substructure of spaces, masterminded progressively, can be settled Special sort of protest called holder; incorporates clients, PC frameworks, printers, and so forth. A coherent subset characterized by security or managerial parameters where particular framework administrator capacities can be effectively portion and designated

Slide 21

Global Catalog AD utilizes a worldwide index with the goal for clients to discover protests immediately, even in a huge multidomain condition GC contains every one of the items in the AD, comprehensive of all spaces and trees in a backwoods, yet with just a subset of their properties. Fills in as a record to the whole structure Serves as an essential issue for client validation

Slide 22

Domain and Forest Functional Levels Windows Server 2008 has 3 backwoods practical levels: Windows 2000 Native Windows 2003 Windows 2008 Windows Server 2008 has 3 area utilitarian levels: Windows 2000 Windows 2003 Windows 2008 Functional level just applies to DC, not part servers. Raising space/woods useful level is irreversible

Slide 23

Sites Address physical system structure A site is an area of your system foundation made up of at least one very much associated IP subnets. Destinations are utilized to permit all AD customers having a place with the same physical system range to get to administrations (DCs, GC and DNS servers) from the servers in closeness, instead of crosswise over moderate, costly WAN connections Sites permit AD have more effective DC replication - can arrange DC replication contrastingly between and intra-locales

Slide 24

Sites and DCs are naturally put into locales when they join the AD area, by IP subnet participation. Subsequent to being put into the site, the DCs start accepting imitated data for their own particular space, and additionally backwoods information.
