+.SH ACCESS CONTROL
+The
+.B shell
+backend does not honor all ACL semantics as described in
+.BR slapd.access (5).
+In general, access to objects is checked by using a dummy object
+that contains only the DN, so access rules that rely on the contents
+of the object are not honored.
+In detail:
+.LP
+The
+.B add
+operation does not require
+.B write (=w)
+access to the 
+.B children
+pseudo-attribute of the parent entry.
+.LP
+The
+.B bind
+operation requires 
+.B auth (=x)
+access to the 
+.B entry
+pseudo-attribute of the entry whose identity is being assessed;
+.B auth (=x)
+access to the credentials is not checked, but rather delegated 
+to the underlying shell script.
+.LP
+The
+.B compare
+operation requires 
+.B read (=r)
+access (FIXME: wouldn't 
+.B compare (=c)
+be a more appropriate choice?)
+to the 
+.B entry
+pseudo-attribute
+of the object whose value is being asserted;
+.B compare (=c)
+access to the attribute whose value is being asserted is not checked.
+.LP
+The
+.B delete
+operation does not require
+.B write (=w)
+access to the 
+.B children
+pseudo-attribute of the parent entry.
+.LP
+The
+.B modify
+operation requires
+.B write (=w)
+access to the 
+.B entry 
+pseudo-attribute;
+.B write (=w)
+access to the specific attributes that are modified is not checked.
+.LP
+The
+.B modrdn
+operation does not require
+.B write (=w)
+access to the 
+.B children
+pseudo-attribute of the parent entry, nor to that of the new parent,
+if different;
+.B write (=w)
+access to the distinguished values of the naming attributes
+is not checked.
+.LP
+The
+.B search 
+operation does not require
+.B search (=s)
+access to the 
+.B entry
+pseudo_attribute of the searchBase;
+.B search (=s)
+access to the attributes and values used in the filter is not checked.

 .SH EXAMPLE
 There is an example search script in the slapd/back-shell/ directory
 in the OpenLDAP source tree.
+.SH LIMITATIONS
+The shell backend does not support threaded environments.
+When using the shell backend, 
+.BR slapd (8)
+should be built
