Description

When we try to parse a DN like "cn=
a b c
", the ComplexDnParser will remove the last space due to this code :

attributeTypeAndValue [Rdn rdn] returns [String upName = ""]
    {
        matchedProduction( "attributeTypeAndValue()" );
        String type = null;
        UpAndNormValue value = new UpAndNormValue();
        String upValue = null;
    }
    :
    (
        ( SPACE { upName += " "; } )*
        type = attributeType { upName += type; }
        ( SPACE { upName += " "; } )*
        EQUALS { upName += "="; }
        ( SPACE 
        { 
            upName += " "; 
            
            if ( upValue == null )
            {
                upValue = " ";
            }
            else
            {
                upValue += " "; 
            } 
        } )*
        attributeValue[value] 
        {
            try
            {
                if ( value.value instanceof String )
                {
                    Object unescapedValue = Rdn.unescapeValue( Strings.trim( (String)value.rawValue ) );
...

Here, the trim method will remove the last space, no matter if there is a backslash before
