Unix in NT Domain Systems. Manish Patel

By mpatel ·
I run a QA Lab for startup company, Company has NT Server Domain systems. In the Lab I have 20 NT server and a PDC(w/ DHCP) & BDC and Exchange Server. I have two+ Sun boxes Ultra 160 and sun 420R Server.
1. How should i artchitec my Sun systems so they can be integrated into NT based Network system?
2. Does Unix have such thing as Domain like PDC and BDC?
My current configuration is for UNIX system are standalone, not part of my network or networked with each other. Thank You.

The answer to your question really depends on how much you would like these systems to be integrated into the "network". Are you looking to just use file/print sharing or would you like people to be able to log into the systems with their NT usernames and passwords. Both of these are fairly easy to setup the later being a bit more difficult to maintain.

The file sharing etc. can be handled witha product caled samba fairly easy to obtain you can get packages for it at http://www.sunfreeware.com/. Just use the pkgadd command to install this package. The configuration shouldn't be much more than reading through the smb.conf file and adding your system name and domain name and plugging in the appropriate pdc name. If you have any questions on the specifics post another question.

Solaris supports PAM configuration meaning you can plug modules in to handle different types of authentication. Right now I know of only two pieces of software that will do this for authentication through smb. Both of them having the caviate that the authenticating user must have a local account on the machine, however their passwords are not used when authenticated over the domain. Pam_smb is my choice for solaris you can get it at http://www.csn.ul.ie/~airlied/pam_smb/. The documentation is fairly complete the only thing I have not seen in the documentation that you will need is to put in your /etc/hosts file the ip of the pdc and bdc followed by their network names. So if your PDC wasPDC1 and it's ip was 10.1.1.2 then you would have the following in your /etc/hosts file.

10.1.1.2 PDC1

Without that you will get acces denied errors even though it seems to be connecting at times. Let me know if you have any questions aboutspecifics on either of these options.

There are even more options than this but these I think are easy open source way of doing it. You can also use anything from LDAP to the a

1. You don't. Or, more correctly, NT domains are for Windows systems only. You can get Samba (a Windows networking implementation for UNIX) and use the Solaris boxes as file servers for Windows clients. You can even have them authenticate the users through your PDC when they access through Samba. This will, however, not automatically log in through any other means, such as ftp or telnet. Or, you can use LDAP to have a common user database for both your Windows and Solaris boxes. For this to work, you should really have Windows 2000 Server rathern than NT since W2K includes an LDAP server.

2. No, and sort of. It all depends on how you set up your networking. The classical way is to use NIS and NFS to implement a shared user database and networking file system. Note that while PDC/BDC centralizes the act of authenticating the users, NIS distributes the user datbase to all systems from a central (primary or backup) NIS server. Not quite the same thing. LDAP can do about the same in a more secure and standardized way. There are also options such as Kerberos. Personally, I would go the LDAP route. It involves some more configuration, but is the best long-term.

Hi there,

The answer to your question is YES and it's free. It's call Sun PcNetlink. I have setup
PcNetlink 1.2 on a Sun Enterprise 450 and it's working like a charm. Very easy to install. It could be a PDC, BDC or even a member server. You could also change is role so it's acting as one of the three mode. You could create user from your /etc/password etc... You could share drives, printers etc...

Try it, you'll see !!!!

If you have more question, fell free to send me an e-mail
