Subject [jira] [Commented] (DIRSHARED-143) Provide helper method to escape characters to be used in LDAP Filter literal
Date Sat, 03 Nov 2012 19:47:12 GMT

    [ https://issues.apache.org/jira/browse/DIRSHARED-143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490082#comment-13490082
] 

Stefan Seelmann commented on DIRSHARED-143:
-------------------------------------------

Another option to create such a filter with escaped special characters is to use the classes
from org.apache.directory.shared.ldap.model.filter package, for example:

{code}
AndNode andNode = new AndNode();
andNode.addNode( new EqualityNode<String>( "uid", new StringValue( "(*)" ) ) );
andNode.addNode( new SubstringNode( "cn", "H*n", null ) );
System.out.println(andNode.toString());
// =>(&(uid=\28\2A\29)(cn=H\2An*))
{code}

I see that it is not always intuitive to use those classes, I think they are not intended
to be used by API users.

> In order to prevent malicious injection, user-provided input must be escaped (the 5 restricted
characters) before being put in LDAP filter.
> Provide a helper static method to make it convenient and available as public API.
