(1)  Section 2.5 (page 5) -- Ref. tags

The text,
                                      vvvvvvvv
   Numerous elements of LDAP are described using ASN.1 [X.680] and are
|  encoded using a particular subset [Protocol, Section 5.2] of the
   Basic Encoding Rules (BER) [X.690].  To allow reuse of
   parsers/generators used in implementing the LDAP "core" technical
   specification [RFC4510], it is RECOMMENDED that extension elements
   (e.g., extension specific contents of controlValue, requestValue,
   responseValue fields) described by ASN.1 and encoded using BER be
|  subjected to the restrictions of [Protocol, Section 5.2].
                                     ^^^^^^^^

(2)  Section 3.1 (page 6), 3rd and 4th paragraph -- Ref. tags

The text:

   An existing operation MAY be extended to return IntermediateResponse
|  messages [Protocol, Section 4.13].
             ^^^^^^^^                                   vvvvvvvv
   Specifications of controls SHALL NOT attach additional semantics to
|  the criticality of controls beyond those defined in [Protocol,
   Section 4.1.11].  A specification MAY mandate the criticality take on
   a particular value (e.g., TRUE or FALSE), where appropriate.

(3)  Section 3.1.2 (page 7), 3rd paragraph -- typo

The text:

   It is RECOMMENDED that designers consider alternative mechanisms for
   providing the function.  For example, an extended operation issued
   subsequent to the Start TLS operation (hence, protected by the
   security layers negotiated by the Start TLS operation) might be used
|  to provided the desired function.

   mechanism for defining new operations.  [...]

|  Unsolicited notifications [Protocol, Section 4.4] offer a capability
   for the server to notify the client of events not associated with the
   operation currently being processed.

(7)  Section 4 (page 9) -- Ref. tags

The text:
                                  vvvvvvvv
|  LDAP allows limited extension [Protocol, Section 4] of the LDAP ASN.1

   Extensions defining LDAP schema elements SHALL provide schema
|  definitions conforming with syntaxes defined in [Models, Section
   4.1].  [...]

(9)  Section 9.1 (page 13) -- duplicate entry

The entry at the bottom of page 13,

   [RFC4512]  Zeilenga, K., "Lightweight Directory Access Protocol
              (LDAP): Directory Information Models", RFC 4512, June
              2006.

should be deleted.
This entry is a duplicate, and it recurs on page 14, at the proper
place according to the collation order (by ascending RFC#).

Notes:

Most important issue:
Apparently, the update of the Reference tags within the text has
been performed incompletely after the assignment of RFC numbers
to those many LDAP I-Ds, leaving 'unsatisfied' tags in the text
(not listed in the References Sections), wherever these tags give
detailed citations, specifying a section or an Appendix there.

The errata detail items below are listed in textual order.
I use change bars and tag lines to emphasize the corrections
proposed and/or the issues in the original text.
Changed text is re-adjusted to conform to RFC formatting rules.
