+.SH OPERATION REQUIREMENTS
+Operations require different privileges on different portions of entries.
+The following summary applies to primary database backends such as
+the LDBM, BDB, and HDB backends. Requirements for other backends may
+(and often do) differ.
+.LP
+The
+.B add
+operation requires
+.B write (=w)
+privileges on the pseudo-attribute
+.B entry
+of the entry being added, and
+.B write (=w)
+privileges on the pseudo-attribute
+.B children
+of the entry's parent.
+.LP
+The
+.B bind
+operation, when credentials are stored in the directory, requires
+.B auth (=x)
+privileges on the attribute the credentials are stored in (usually
+.BR userPassword ).
+.LP
+The
+.B compare
+operation requires
+.B compare (=c)
+privileges on the attribute that is being compared.
+.LP
+The
+.B delete
+operation requires
+.B write (=w)
+privileges on the pseudo-attribute
+.B entry
+of the entry being deleted, and
+.B write (=w)
+privileges on the
+.B children
+pseudo-attribute of the entry's parent.
+.LP
+The
+.B modify
+operation requires
+.B write (=w)
+privileges on the attibutes being modified.
+.LP
+The
+.B modrdn
+operation requires
+.B write (=w)
+privileges on the pseudo-attribute
+.B entry
+of the entry whose relative DN is being modified,
+.B write (=w)
+privileges on the pseudo-attribute
+.B children
+of the old and new entry's parents, and
+.B write (=w)
+privileges on the attributes that are present in the new relative DN.
+.B Write (=w)
+privileges are also required on the attributes that are present
+in the old relative DN if
+.B deleteoldrdn
+is set to 1.
+.LP
+The
+.B search
+operation, for each entry, requires
+.B search (=s)
+privileges on the attributes that are defined in the filter.
+Then, the resulting entries are tested for
+.B read (=r)
+privileges on the pseudo-attribute
+.B entry
+(for read access to the entry itself)
+and for
+.B read (=r)
+access on each value of each attribute that is requested.
+Also, for each
+.B referral
+object used in generating continuation references, the operation requires
+.B read (=r)
+access on the pseudo-attribute
+.B entry
+(for read access to the referral object itself),
+as well as
+.B read (=r)
+access to the attribute holding the referral information
+(generally the
+.B ref
+attribute).
+.LP
+Some
+.B controls
+require specific access privileges.
+The
+.B proxyAuthz
+control requires
+.B auth (=x)
+privileges on all the attributes that are present in the search filter
+of the URI regexp maps (the right-hand side of the
+.B sasl-regexp
+directives).
+It also requires
+.B auth (=x)
+privileges on the
+.B saslAuthzTo
+attribute of the authorizing identity and/or on the
+.B saslAuthzFrom
+attribute of the authorized identity.
