Deployment Aids

• Sysprep used to help deploy Server and Advanced Server.– Sysprep prepares a Pro or Server

installation for duplication to identical hardware.• Run sysprep, cut an image, copy image• Deletes security identifiers, user and system

specific data• Regenerates on reboot

Deployment

• Remote OS Installation– Server hosted equivalent CD

• Remote Installation Service

– Requires DNS, DHCP, Active Dir.– Installed on a shareable volume– Can’t be on the server’s system drive

• Formatted as NTFS

Command Interface

• Start / Run / Command– Example

• Netstat /?

Naming Conventions

• Distinguished Name DN– Defines the domain and the related containers in

which the object resides.

• Relative Distinguished Name RDN– An attribute of an object

• Globally Unique Identifier – Avoids duplication, ensures uniqueness, a 128 bit

number assigned to an object on creation and stored with it.

Naming Conventions

• User Principal Name UPN– Combines the user account name with the

domain name where the account exists

• Domain Component DC

• Organizational Unit OU

• Common Name CN

Microsoft & Directory Services

• MS does not support an extension of LDAP, called LDAP Duplication Update Protocol.– Violation of directory rules can lead to

cascading errors in directory– Uses synchronization to populate and update

directories

Microsoft & Directory Services

• Microsoft left out major portions of the X.500 protocol in the AD.– B/C Dependent on OSI networking layer and

lack of public interest.– Elements include:

• Dir. Access Prot, Dir. Systems Prot., Dir Info Shadowing Prot.,Dir Operational Binding Management Prot.

What is a directory service?

• A directory is like a database, but tends to contain more descriptive, attribute-based information. The information in a directory is generally read much more often than it is written.

• Directory updates are typically simple all-or-nothing changes, if they are allowed at all.

• Directories are tuned to give quick-response to high-volume lookup or search operations.

LDAP

• Lightweight Directory Access Protocol.

• A directory service protocol that runs over TCP/IP.

• The details of LDAP are defined in RFC 1777 "The Lightweight Directory Access Protocol."

LDAP

• The LDAP directory service model is based on entries.

• An entry is a collection of attributes that has a name, called a distinguished name (DN).

• Each of the entry's attributes has a type and one or more values.

LDAP

• Types are typically mnemonic strings, like "cn" for common name, or "mail" for email address. – mail attribute might contain the value

"bdobs@psu.edu– jpegPhoto attribute would contain a

photograph in jpeg format

How is the information arranged?

• Directory entries are arranged in a hierarchical tree-like structure that reflects political, geographic and/or organizational boundaries.

• Entries representing countries appear at the top of the tree.

• Below them are entries representing states or national organizations.

• Below them might be entries representing people, organizational units, printers, documents,

LDAP Tree

C=GB C=US

O=PSU

CN=Rick Evans

CN=Richard Evans

mail=revans@psu.edu

How is the information referenced?

• Entry is referenced by its distinguished name, constructed by taking the name of the entry itself (called the relative distinguished name, or RDN) and concatenating the names of its ancestor entries.– For example, the entry for Rick Evans in the example

above has an RDN of "cn=Rick Evans" and a DN of "cn=Rick Evans, o=PSU, c=US". The full DN format is described in RFC 1779, "A String Representation of Distinguished Names."

Trusts

• Two-way transitive trust– Automatically achieved between domains in

the same tree or can be established between domains on separate trees.

• Explicit one-way trust– Created between specific domains in two

different forests and provide one-way restricted permissions.

Domain Trees & Child Domains

• When should a child be created?– Is decentralized administration desired– Do you need tight/localized administration– Do business activities dictate separate

domains– Do account policies need to differ

Domain Trees & Child Domains

• When should a forest be created?– Are the business activities extremely different?– Are there reasons for maintaining separate identities

• Unique trade names

– Do joint venture or partner relationships exist that require tighter control over network resources.

• Enforcing direct administrative and security restrictions

User accounts

• Unique identifier– SID – security identifier– User and group SID’s form the security token– Unique, must be regenerated if account is

deleted.– Mapped to the Access control list

• DACL – discretionary access control list is a security descriptor, who has permission to use.

Profiles

• Local User – maintained on each system in the users profile directory.

• Roaming – allows users to move from system to system, located in shared directory of server.

• Mandatory – restricted by sysadmin to permit consistent desktops.– Ntuser.dat to Ntuser.man

NetWare

• NetWare Loadable Modules NLM’s– Add hardware without rebooting– Remove without stopping server– Increase volume size while S is running

• Multiprocessor kernel MPK• Supports symmetrical multiprocessing H/W (SMP)• Multithreading• Up to 32 processors - Questionable release date

NetWare

• NetWare Directory Services– Organizes users, groups, devices into a tree

– Single user login– Scalable, up to unlimited sizing

• 1999 test had a billion users

NetWare

• Novell's core-services are wrapped around NDS eDirectory, a robust, cross-platform directory service.

• NDS eDirectory ships with NetWare 5.1 and is available in versions that run natively on Linux, Solaris, and Windows 2000 and NT - no NetWare required.

NetWare

• NDS - NetWare's central feature. All the services that ship in the NetWare 5.1 box, all those available from Novell separately and even most third-party additions plug into the directory to become part of a fabric of integrated services.

• This integration gives administrators a replicated, fail-safe, single point of administration.

• Users, get one place to search for enterprise wide resources and one point of authentication to gain access to those resources.

NetWare

• Fault tolerance (3 Levels)– SFT1 single server, when a sector goes bad,

the bad sector to a good one. Hot fix.• Redundant volume data structures

– SFTII level two, has all the features of one and uses disk mirroring and duplexing

• Duplexing has a controller for each drive

Mirror

Duplex

• Fault tolerance (Cont)– SFTIII Level three consists of SFT II plus

server mirroring, or redundant servers.– Two servers connected using a high speed

Mirrored Server Link (MSL)– Nonstop operation using an entirely

redundant server.

NetWare 5.1's security

• NetWare 5.1 automatically creates a directory-based CA and generates a server certificate, which it uses for the Web-accessible NetWare Management Portal (NMP) and the Enterprise Web Server.

NetWare 5.1's security

• SSL-enabled and secure out of the box with NetWare 5.1

• NetWare supports minimum password lengths, intruder detection lockout and unique passwords– does not have a built-in method for

identifying weak passwords or forcing users to use punctuation marks or other special characters in their passwords.
