Retrieves additional paragraphs that should be included in the description for this tool. Retrieves a set of controls that should be included in any bind request generated by this tool.

Retrieves the connection options that should be used for connections that are created with this command line tool. Retrieves a set of information that may be used to generate example usage information. Retrieves a set containing any short identifiers that should be suppressed in the set of generic tool arguments so that they can be used by a tool-specific argument instead.

It is very common for many applications to have to authenticate its users or login. At the. First, one must know which libraries have to be imported, or if any of these libraries must be installed. To use the LDAP server, only the following libraries are needed:. To connect to the server, one must load into a Hashtable all the fields we want to send URL for the connection, user credentials, authentication type, and others that may be necessary , for example:.

In case of not being able to connect to the server with user credentials, an exception will appear NamingException. Once connected to the server, we can get the context that allows us to make inquiries, information, authenticate, etc. To log off, one must simply type:. In order to do so, all one must do is log oneself in a similar manner to that discussed in the previous example, but indicating the corresponding username and password. If you are able to get connected, you can obtain the context, and if you do not have the correct username or password, the same exception as before will appear:.

To do so, one must first get the connection context as indicated above either as an administrator or common user, but it may depend on the LDAP server. Then, we need to indicate how many and what are the names of the attributes we want which could, potentially, be none, if we just want to check whether a user who meets the conditions exists , and the filtering conditions which are always important although they might be random.

For example, many email client have the ability to use an LDAP server as an address book, and many web containers have support for authenticating against an LDAP server. But there are also numerous applications and utilities whose core purpose involves LDAP communication.

If you need other values, you can use the extra keys mechanism. This works by adding path components to the LDAP path in the above payload. The only requirement is that your UUID is the last item in the list. View Connections.
