Emmanuel Lécharny updated DIRAPI-395:
-------------------------------------
Affects Version/s: 2.1.5
> Improve unescaped backslash handling in DESC for IBM's directory servers
> ------------------------------------------------------------------------
>
> Key: DIRAPI-395
> URL: https://issues.apache.org/jira/browse/DIRAPI-395
> Project: Directory Client API
> Issue Type: Improvement
> Affects Versions: 2.1.5
> Reporter: Hiroyuki Wada
> Priority: Major
> Fix For: 2.1.6
>
>
> IBM Security Verify Directory (formerly known as IBM Security Directory
> Server, and previously as IBM Tivoli Directory Server) uses Non-comliant LDAP
> schema definitions. Specifically, there are cases where DESC contains
> unescaped backslashes, like the following example.
> {noformat}
> attributeTypes: ( 1.3.18.0.2.4.575 NAME 'role' DESC 'Based on CIM. A free
> form string describing the role of the Processor - for example, \Central
> Processor\ or \Math Processor\.' EQUALITY 2.5.13.2 SYNTAX
> 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE )
> {noformat}
> Unfortunately, in the current implementation, the position of backslash can
> lead to error. For example, parsing the above schema using the
> AttributeTypeDescriptionSchemaParser results in a
> java.lang.ArrayIndexOutOfBoundsException.
> {noformat}
> Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 118 out of bounds
> for length 118

> To address this issue, I've wrote a patch that allows unescaped backslash in
> DESC during parsing when quirks mode is enabled. I have pushed the
> implementation to the following GitHub URL:
> https://github.com/openstandia/directory-ldap-api/commits/improve-desc-escape
> If this improvement is welcome, I would like to submit a pull request.
