How can you configure LDAP domain controller in Red Hat Enterprise Linux 4?
To configure LDAP domain controller in Red Hat Enterprise Linux 4, import the users from the LDAP server with the use of the domain server. Then login using the LDAP and reduce the DNS LDAP priority on the settings.
What is clientserver computing?
Client/server computing, as opposed to Peer to Peer computing, is when there is a directory server present on the network, such as Windows Server 200x, LDAP, Novell eDirectory, or an equivelant. This server acts as a central authority for computers on the network.
What is the function of an LDAP query?
A LDAP query is a configurable search used to gather information from your directory server. It can be used to test whether certain data exists on the server.
When you are binding to an LDAP server what information is passed between the server and LDAP client?
The client IP address, the clients host name, the port address to use during communication
How you can raise domain functional level of 2003 server?
server 2003 Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2 After you upgrade all Windows NT 4.0-based domain controllers in a domain to Windows Server 2003, you can raise the functional level of each domain in the forest to Windows Server 2003. Before you raise the domain functional level, however, you must ensure that no Windows NT 4.0-based domain controllers remain in the domain. Warning * If Windows NT 4.0-based domain controllers are running in a domain when you raise the domain functional level to Windows Server 2003, they will no longer be able to communicate with the new Windows Server 2003 domain controllers and will not receive necessary updates. Use the following LDAP query to identify any Windows NT 4.0 domain controllers remaining in the domain. Run the LDAP query against the Domain container in Active Directory Users and Computers. If you have not manually changed the value of the operatingSystemVersion attribute of the computer object, this query is conclusive for domain controllers running Windows NT 4.0. You must be a member of the Domain Admins group to run the following query. To identify Windows NT 4.0-based domain controllers in a domain 1. From any Windows Server 2003-based domain controller, open Active Directory Users and Computers. 2. If the domain controller is not already connected to the appropriate domain, connect it to the domain as follows: a. Right-click the current domain object, and then click Connect to domain. b. In the Domain dialog box, type the DNS name of the domain that you want to connect to, or click Browse to select the domain from the domain tree, and then click OK. 3. Right-click the domain object, and then click Find. 4. In the Find dialog box, click Custom Search. 5. Click the domain for which you want to change the functional level. 6. Click the Advanced tab. 7. In the Enter LDAP query box, type the following, leaving no spaces between any characters (the query is not case-sensitive): (&(objectCategory=computer)(operatingSystemVersion=4*)(userAccountControl:1.2.840.113556.1.4.803:=8192)) 8. Click Find Now. This produces a list of the computers in the domain that are running Windows NT 4.0 and functioning as domain controllers. A domain controller might appear in the list for any of the following reasons: * The domain controller is running Windows NT 4.0 and must be upgraded. * The domain controller has been upgraded to Windows Server 2003, but the change has not replicated to the target domain controller. * The domain controller is no longer in service, but its computer object has not been removed from the domain. Before you can change the domain functional level to Windows Server 2003, you must physically locate any domain controller in the list, determine its current status, and either upgrade or remove the domain controller as appropriate.

What is LDP?A: The Lightweight Directory Access Protocol, or LDAP is an application protocol for querying and modifying directory services running over TCP/IP.[1]A directory is a set of objects with attributes organized in a logical and hierarchical manner. The most common example is the telephone directory, which consists of a series of names (either of persons or organizations) organized alphabetically, with each name having an address and phone number attached.An LDAP directory tree often reflects various political, geographic, and/or organizational boundaries, depending on the model chosen. LDAP deployments today tend to use Domain name system (DNS) names for structuring the topmost levels of the hierarchy. Deeper inside the directory might appear entries representing people, organizational units, printers, documents, groups of people or anything else that represents a given tree entry (or multiple entries).Its current version is LDAPv3, which is specified in a series of Internet Engineering Task Force (IETF) Standard Track Requests for comments (RFCs) as detailed in RFC 4510.LDAP means Light-Weight Directory Access Protocol. It determines how an object in an Active directory should be named. LDAP (Lightweight Directory Access Protocol) is a proposed open standard for accessing global or local directory services over a network and/or the Internet. A directory, in this sense, is very much like a phone book. LDAP can handle other information, but at present it is typically used to associate names with phone numbers and email addresses. LDAP directories are designed to support a high volume of queries, but the data stored in the directory does not change very often. It works on port no. 389. LDAP is sometimes known as X.500 Lite. X.500 is an international standard for directories and full-featured, but it is also complex, requiring a lot of computing resources and the full OSI stack. LDAP, in contrast, can run easily on a PC and over TCP/IP. LDAP can access X.500 directories but does not support every capability of X.500What is REPLMON?A: Replmon is the first tool you should use when troubleshooting Active Directory replication issues. As it is a graphical tool, replication issues are easy to see and somewhat easier to diagnose than using its command line counterparts.

Which dns record type is required by active directory t allow clients to locate ad resources?
SRV Resource Records When a Windows 2000-based domain controller starts up, the Net Logon service uses dynamic updates to register SRV resource records in the DNS database, as described in "A DNS RR for specifying the location of services (DNS SRV) The SRV record is used to map the name of a service (in this case, the LDAP service) to the DNS computer name of a server that offers that service. In a Windows 2000 network, an LDAP resource record locates a domain controller. A workstation that is logging on to a Windows 2000 domain queries DNS for SRV records in the general form: _Service ._ Protocol . DnsDomainName Active Directory servers offer the LDAP service over the TCP protocol; therefore, clients find an LDAP server by querying DNS for a record of the form: _ldap._tcp. DnsDomainName _msdcs Subdomain There are possible implementations of LDAP servers other than Windows 2000-based domain controllers. There are also possible implementations of LDAP directory services that employ Global Catalog servers but are not servers that are running Windows 2000. To facilitate locating Windows 2000-based domain controllers, in addition to the standard _ Service ._ Protocol . DnsDomainName format, the Net Logon service registers SRV records that identify the well-known server-type pseudonyms "dc" (domain controller), "gc" (Global Catalog), "pdc" (primary domain controller, and "domains" (globally unique identifier, or GUID) as prefixes in the _msdcs subdomain. This Microsoft-specific subdomain allows location of domain controllers that have Windows 2000-specific roles in the domain or forest, as well as the location by GUID when a domain has been renamed. To accommodate locating domain controllers by server type or by GUID (abbreviated "dctype"), Windows 2000-based domain controllers register SRV records in the following form: _ Service ._ Protocol . DcType ._msdcs. DnsDomainName The addition of the _msdcs subdomain means that two sets of DNS names can be used to find an LDAP server: DnsDomainName is used to find an LDAP server or Kerberos server that is running TCP (or, in the case of a Kerberos server, either TCP or the User Datagram Protocol [UDP]), and the subdomain _msdcs. DnsDomainName is used to find an LDAP server that is running TCP and also functioning in a particular Windows 2000 role. The name "_msdcs" is reserved for locating domain controllers. The single keyword "_msdcs" was chosen to avoid cluttering the DNS namespace unnecessarily. Other constant, well-known names (pdc, dc, and gc) were kept short to avoid exceeding the maximum length of DnsDomainName.

What is the difference between LDAP and Active Directory?
What i can make out is AD is a proprietary concept developed by Microsoft and LDAP is more open and more general protocol for managing directories in a client-server organization. AD features are limited in that it supports only windows based machine whereas LDAP supports multi platform computers to access directories in the server. Correct me if i am wrong.
