Apache ldap windows

The OpenLDAP libraries do not support referral and rebind when the client has perfomed a simple bind. This is due to serious security concerns as a simple bind presents the server with a plain text password. Automatic referral of simply bound connections would simply make it much too easy for a rogue server to harvest passwords.

I have also found information that show how to make a simple query work by querying the Global Catalog instead of a normal LDAP query to a particular Domain Controller. Using the LDAP moniker instructs the query to perform a search using a full replica of the Active Directory database in a domain and, depending on the query, possibly all subdomains.

In contrast, using the GC moniker instructs the query to search a global catalog server, which contains a partial replica of its domain and all of its child domains. Consequently, if you query a global catalog server in the root domain, the query contains data from all domains in the forest. Therefore, if all attributes that you want to query are contained in the global catalog, it is more efficient to query this data source than to search one or more full replicas of the Active Directory database in the forest.

My initial discovery of being able to do it was found in this mail archive. And by making it secure, Apache will also support referral chasing. In order to do this, Apache must trust the certificate that the Domain Controller has installed.

First, we need to create a Firewall rule on the Windows domain controller. This firewall rule will allow the Apache server to query the Active directory database.

On the domain controller, open the application named Windows Firewall with Advanced Security Create a new Inbound firewall rule. Select the TCP option. Select the Specific local ports option. Enter the TCP port Congratulations, you have created the required firewall rule. This rule will allow the Apache server to query the Active directory database.

The ApacheDS 2. The RCP application is based on the latest version of Eclipse 3. There are a lot more new additions, improvements and bug fixes see release notes. Apache Directory Studio 2. A new ApacheDS 2. If a simple attribute comparison is all that is required, the comparison operation performed by ldap-attribute will be faster than the search operation used by ldap-filter especially within a large directory.

The next example demonstrates the power of using filters to accomplish complicated administrative requirements. Without filters, it would have been necessary to create a new LDAP group and ensure that the group's members remain synchronized with the pager users.

This becomes trivial with filters. The goal is to grant access to anyone who has a pager, plus grant access to Joe Manager, who doesn't have a pager, but does need to access the same resource:.

This last may look confusing at first, so it helps to evaluate what the search filter will look like based on who connects, as shown below. If Fred User connects as fuser , the filter would look like. The above search will only succeed if fuser has a pager. When Joe Manager connects as jmanager , the filter looks like. If the attribute field contains the username, common name and telephone number of a user, a CGI program will have access to this information without the need to make a second independent LDAP query to gather this additional information.

This has the potential to dramatically simplify the coding and configuration required in some web applications. An Active Directory installation may support multiple domains at the same time. To distinguish users between domains, an identifier called a User Principle Name UPN can be added to a user's entry in the directory.

This UPN usually takes the form of the user's account name, followed by the domain components of the particular domain, for example somebody nz. In this way both somebody nz. To make this practical, Active Directory supports the concept of a Global Catalog.

This Global Catalog is a read only copy of selected attributes of all the Active Directory servers within the Active Directory forest. Querying the Global Catalog allows all the domains to be queried in a single query, without the query spanning servers over potentially slow links.

If enabled, the Global Catalog is an independent directory server that runs on port for SSL. To search for a user, do a subtree search for the attribute userPrincipalName , with an empty search root, like so:.

Users will need to enter their User Principal Name as a login, in the form somebody nz. Unfortunately, it is not possible to just change to LDAP authentication by adding the proper directives, because it will break the Permissions forms in the FrontPage client, which attempt to modify the standard text-based authorization files. Once a FrontPage web has been created, adding LDAP authentication to it is a matter of adding the following directives to every.

FrontPage restricts access to a web by adding the Require valid-user directive to the. This means that anybody who has an entry in the LDAP directory is considered a valid user, whereas FrontPage considers only those people in the local user file to be valid. By substituting the ldap-group with group file authorization, Apache is allowed to consult the local user file which is managed by FrontPage - instead of LDAP - when handling authorizing the user.

Once directives have been added as specified above, FrontPage users will be able to perform all management operations from the FrontPage client.

This directive allows you to override the prefix used for environment variables set during LDAP authorization. By default, subsequent authentication providers are only queried if a user cannot be mapped to a DN, but not if the user can be mapped to a DN and their password cannot be verified with an LDAP bind. An optional DN used to bind to the server when searching for entries. A bind password to use in conjunction with the bind DN.

Note that the bind password is probably sensitive data, and should be properly protected. If the value begins with exec: the resulting command will be executed and the first line returned to standard output by the program will be used as the password.
