Types

Setup a connection to an LDAP server, the HOST's are tried in order.

Types

Setup a connection to an LDAP server, the HOST's are tried in order.

The log function takes three arguments, fun(Level, FormatString, [FormatArg]) end.

Timeout set the maximum time in milliseconds that each server request may take.

All TCP socket options are accepted except active, binary, deliver, list, mode and packet

Types

Shutdown the connection after sending an unbindRequest to the server. If the connection is tls the connection will be closed with ssl:close/1, otherwise with gen_tcp:close/1.

Same as start_tls(Handle, Options, infinity)

Types

Upgrade the connection associated with Handle to a tls connection if possible.

The upgrade is done in two phases: first the server is asked for permission to upgrade. Second, if the request is acknowledged, the upgrade to tls is performed.

Error responses from phase one will not affect the current encryption state of the connection. Those responses are:

tls_already_started

The connection is already encrypted. The connection is not affected.

{response,ResponseFromServer}

The upgrade was refused by the LDAP server. The ResponseFromServer is an atom delivered byt the LDAP server explained in section 2.3 of rfc 2830. The connection is not affected, so it is still un-encrypted.

Errors in the second phase will however end the connection:

Error

Any error responded from ssl:connect/3

The Timeout parameter is for the actual tls upgrade (phase 2) while the timeout in eldap:open/2 is used for the initial negotiation about upgrade (phase 1).

Types

Authenticate the connection using simple authentication.

Types

Add an entry. The entry must not exist.

  add(Handle,
      "cn=Bill Valentine, ou=people, o=Example Org, dc=example, dc=com",
       [{"objectclass", ["person"]},
        {"cn", ["Bill Valentine"]},
        {"sn", ["Valentine"]},
        {"telephoneNumber", ["545 555 00"]}]
     )

Types

Delete an entry.

  delete(Handle, "cn=Bill Valentine, ou=people, o=Example Org, dc=example, dc=com")

Types

Create an add modification operation.

Types

Create a delete modification operation.

Types

Create a replace modification operation.

Types

Modify an entry.

  modify(Handle, "cn=Bill Valentine, ou=people, o=Example Org, dc=example, dc=com",
         [eldap:mod_replace("telephoneNumber", ["555 555 00"]),
	  eldap:mod_add("description", ["LDAP Hacker"]) ])

Types

Modify the password of a user. See modify_password/4.

Types

Modify the password of a user.

• Dn. The user to modify. Should be "" if the modify request is for the user of the LDAP session.

• NewPasswd. The new password to set. Should be "" if the server is to generate the password. In this case, the result will be {ok, GenPasswd}.

• OldPasswd. Sometimes required by server policy for a user to change their password. If not required, use modify_password/3.

Types

Modify the DN of an entry. DeleteOldRDN indicates whether the current RDN should be removed from the attribute list after the operation. NewSupDN is the new parent that the RDN shall be moved to. If the old parent should remain as parent, NewSupDN shall be "".

  modify_dn(Handle, "cn=Bill Valentine, ou=people, o=Example Org, dc=example, dc=com ",
            "cn=Bill Jr Valentine", true, "")

Types

Search the directory with the supplied the SearchOptions. The base and filter options must be supplied. Default values: scope is wholeSubtree(), deref is derefAlways(), types_only is false and timeout is 0 (meaning infinity).

  Filter = eldap:substrings("cn", [{any,"V"}]),
  search(Handle, [{base, "dc=example, dc=com"}, {filter, Filter}, {attributes, ["cn"]}]),

The timeout option in the SearchOptions is for the ldap server, while the timeout in eldap:open/2 is used for each individual request in the search operation.

Search baseobject only.

Search the specified level only, i.e. do not recurse.

Search the entire subtree.

Never derefrence aliases, treat aliases as entries.

Always derefrence aliases.

Derefrence aliases only when searching.

Derefrence aliases only in finding the base.

Types

Create a filter which filters on attribute type presence.

Types

Create a filter which filters on substrings.

Types

Create a equality filter.

Types

Create a greater or equal filter.

Types

Create a less or equal filter.

Types

Create a approximation match filter.

Types

Creates an extensible match filter. For example,

  eldap:extensibleMatch("Bar", [{type,"sn"}, {matchingRule,"caseExactMatch"}]))

creates a filter which performs a caseExactMatch on the attribute sn and matches with the value "Bar". The default value of dnAttributes is false.

Types

Creates a filter where all Filter must be true.

Types

Create a filter where at least one of the Filter must be true.

Types

Negate a filter.
