What is Domain Services for Windows? Domain Services for Windows (DSfW) is a suite of technologies Provides AD style authentication to users, applications eDirectory ™ users can access AD resources and applications with a cross forest trust in place Access to Open Enterprise Server services like file and print services hosted on Novell Storage Services ™ or POSIX file systems is unchanged
DSfW: What Does It Achieve? eDirectory ™ Tree Active Directory Forest DSfW DSfW Cross Forest Trust Resource Access eDirectory User Windows User AD Style Authentication MMC Add/Modify User iManager Clientless Access Applications
Benefits of DSfW Access Novell ® Open Enterprise Server (OES) file system without a Novell Client ™ on the workstation Single Identity and single login to access resources from Linux, AD and other services Standardized administration tool in a heterogeneous environment Applications needing AD style Authentication can be seamlessly used with OES deployments Integration of Windows desktops into a Linux environment Leverage existing eDirectory ™ tree to create a AD forest without rip-and-replace.
Prerequisites for Successful Implementation
Understand What You Are Trying To Achieve with DSfW
Client-less authentication and access to Novell ® resources?
Access to AD applications?
Check if Windows based application is going to work with DSfW
Can it be in a DSfW Forest? (NetApp, Citrix)
Does it need an AD forest with Trust established (SharePoint)
Examine your existing eDirectory ™ structure: eDirectory designs with a hierarchical structure of Organization objects is more suited for DSfW than a flat structure Domain Name: The first DSfW servers DNS Suffix needs to match the AD Domain Name and suffix. For example if your AD domain name is dc=novell,dc=com then the DNS Suffix needs to be novell.com Schema checks: Check your schema in accordance with Novell ® TID 7003431 Partitioning and replication: Check the general tree health and how the existing partitions map to DSfW Planning Considerations
DSfW into an existing tree
eDirectory ™ versions need to be up to date.
At least one existing eDirectory 8.8 Server should be in the tree with the rest at 8.73.10 or later.
Put at least one Open Enterprise Server 2 Linux Server in place to begin with with any NetWare ® 6.5 Servers on SP8
Time synchronization is key. Kerberos is also time sensitive
New Domain Non-Name Mapped Configuration
eDirectory ™ tree is new
The AD Forest is created at the Tree Root as a hierarchy of DC objects.
The DC objects are actual eDirectory objects
User administrator is created in cn=administrator,cn=users,dc=example,dc=com
server 1 server 2 server 3 server 4 server 5 dc=example, dc=com Domain Controllers
New Domain Non-Name Mapped Configuration Why would this be used?
Single Server Tree
New Tree just for DSfW. No other Novell ® application considerations
The eDirectory ™ Tree Administrator is also the DSfW Administrator. No eDirectory user called admin is created
A domain is automatically mapped to the eDirectory container e.g. domain acme.com is mapped to container dc=acme,dc=com
Into Existing eDirectory ™ Trees Name-Mapped Configuration Characteristics
An existing eDirectory Tree's partitioned container is used to map the DSfW domain
The eDirectory Tree Administrator is different from the First Domain Administrator
The domain mapping to eDirectory Tree is managed by the eDirectory Tree Administrator
Into Existing eDirectory ™ Trees Name-Mapped Configuration Why would this be used ?
To add DSfW to an existing eDirectory environment
To allow the use of Novell Workstations without the Novell Client ™
To preserve use of existing Novell based applications such as GroupWise ® and the Novell Client
Microsoft Applications access can be established through an AD style trust
Demonstration of Deployment
Deployment of DSfW into An Existing eDirectory ™ Tree Existing NetWare ® 6.5 SP8 Tree – Novell ® -Tree Open Enterprise Server 2 SP2 Server has already been part configured and joined to the tree The DSfW provisioning wizard needs to run Once deployed examine how access can be given to Microsoft Clients to data volumes hosted on the NetWare Server
DSfW in Open Enterprise Server 2 SP2 and Beyond
DSfW in Open Enterprise Server 2 SP2
Enhanced install with a new provisioning wizard
SYSVOL information replicated to Additional Domain Controllers
Existing password policies are honored
Support channel and media upgrade from OES2SP1
DSfW Provisioning Wizard Allows autoYaST to configure a basic Open Enterprise Server 2 SP2 system. A Java-based wizard is then used Gives more control and management over the DSfW install process than OES2 SP1 Gives the opportunity for remedial action if an installation stage fails. Each stage can be executed multiple times until successful Is only run when the base OS is installed and operational Can be scripted if required
DSfW Provisioning Wizard
SYSVOL Replication SYSVOL stores information about Group Policies SYSVOL information replicated to Additional Domain Controllers thus ensuring load balancing and fault tolerance Uses rsync to accomplish the synchronization Similar functionality to native Windows 2003 Domain Controller
Password Policies Extended YaST configuration to retain the existing password policy association on the domain users For each new group policy, a corresponding password policy is created in cn=Password Policies, cn=systems, dc=<do main> gpo2nmas can handle multiple group polices gposync.sh will build a list of group policies and run gpo2nmas for each of them crontab will run gposync.sh once every 30 minutes
Upgrade Channel and media upgrade supported. Upgrade Sequence: PDC first, ADCs later. Multiple PDC SRV records from DNS will be removed sshd, rsync configuration files are changed Mixed version environment is supported
DSfW in OES2 SP3 Removing Partition Boundary Limitation DNS configuration on ADC Deployment limiters addressed
Master Replica not mandatory on the Domain Controller
Disconnected child domains in a eDirectory ™ tree
Domain name need not be the eDirectory container name
Windows 2008 member server support
Third Party Application Support
Supported configuration for Citrix XENDesktop and DSfW: http://support.citrix.com/article/CTX123281
XenDesktop 3 and 4 are supported when used in an environment with Novell ® Domain Services for Windows (DSfW) in Open Enterprise Server 2 Support Pack 1 and higher as follows:
The XenDesktop farm must be configured to use registry-based controller discovery, as documented in KB article CTX118976 - How to Configure XenDesktop to Function Properly Without an Organizational Unit in Active Directory, and all Desktop Delivery Controllers and virtual desktops must be a member of the same “Domain Services for Windows” domain. There is no requirement for Novell Client ™ software to be installed either on the Desktop Delivery Controllers or the virtual desktops
