Date Fri, 17 Dec 2010 20:38:01 GMT

    [ https://issues.apache.org/jira/browse/DIRSTUDIO-714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972638#action_12972638

Stefan Seelmann commented on DIRSTUDIO-714:
-------------------------------------------

>From RFC 4517, section 4.1 (http://tools.ietf.org/html/rfc4512#section-4.1):

     AttributeTypeDescription = LPAREN WSP
        ... 
        [ SP "DESC" SP qdstring ]     ; description
        ...

      qdstring = SQUOTE dstring SQUOTE
      qstring = 1*( QS / QQ / QUTF8 )   ; escaped UTF-8 string

      QQ =  ESC %x32 %x37 ; "\27"                                           <---------
single quote must be escaped
      QS =  ESC %x35 ( %x43 / %x63 ) ; "\5C" / "\5c"

      ; Any UTF-8 encoded Unicode character
      ; except %x27 ("\'") and %x5C ("\")
      QUTF8    = QUTF1 / UTFMB

> I was trying to import the schema from our OpenDS server.  I received a parse failure
error.  I think it's due to the description containing a single quote character (') which
is not being escaped.
> To test this, set up a default OpenDS server, and try to use Dir Studio to edit its schema.
> The failure I see is:
> null
