The latest release of mod_psldap provides new core capabilities to support new actions to register users, add ldap attributes and client side drag and drop editing of the LDAP records to reassign records to superiors, people to managers, and members to groups. A client side form validation framework was also introduced that simplifies validation through leverage of custom attributes on the input elements.

  • Fixed DocumentManager JS API to accomodate browser technology changes – mod_psldap now supports XSLT on the client without a round trip to the server to reaquire the XML and reset the default XSL
  • Addition of search status update in the tree div and processing status to the record editing div in alt_index.html
  • Implemented window resizing to fit content in editable forms popups
  • Enabled anonymous access through the module when a user is not provided
  • Implemented a Register action to force rebinding to ldap with credentials provided through the PsLDAPRegBindDN and PsLDAPRegBindPassword parameters configured in the Apache configuration for the module
  • Modified the DSML_editform.xsl to transform for registration specific view provided the dn attribute on the searchResultEntry node equals ‘dc=registered’
  • Added operational attributes into the attribute set returned when an LDAP search is executed, allowing visibility to entryUUID, modifyTimestamp, createTimestamp, creatorsName, among other attributes
  • Eliminated potential security hole when using cookie based sessions
  • Modified LDAP session persistance to pull timestamp from the operational attribute modifyTimestamp to dtermine last access time for Apache session
  • Secured session cookies with HttpOnly option to reduce XSS attack risk – pending identification of browser support
  • Introduced validation framework in edit tools – invokes any function set in the psvalidate attribute of an input element in the context of the input element on form validation passing the argument list identified in a comma separate string following the function name in the attribute e.g. psvalidate=’psldap_validateMinLength,7′
  • Introduced 4 standard validation methods: psldap_validateMinLength, psldap_validateMaxLength, psldap_validateEMail, psldap_validatePasswordStrength,
  • Fixed the configure script – the generated Makefile now provides reliable builds, installs, and bundling of the module
  • Enable drag and drop movement across organizational units and managers in the explorer tree via mouse actions against the image handles on each tree node

Version 0.92 (released 03 April 2010)

This is a patch fix against 0.91 to address defects identified in extended testing. This is a bug fix release to address variations on the initially tested configurations and restores isolation of site specific configurations to simplify an upgrade.

  • Moved common capabilities back out of DSML_sitefrags.xsl to leave that stylesheet for site specific customizations only – common capabilities are now in DSML_commonscript.xsl
  • Refactored the pageHeader template with pageHeaderWithRefClass to reduce duplicate code
  • Removed some hardcoded values from the DSML_vendors.xsl (enabled automatic population of the ldapDomains to all select elements with an id of ‘dn’) and made the template for servicesMgmt site specific
  • Corrected minor title setting bug on commonscript XSL
  • Extended vcard to include KEY, REV, PRODID, and CLASS, also fixing IM references to be compliant with RFC 4770
  • Fixed generated dsml structure to better match spec – pushed searchResponse back under a batchResponse node and change mgmt and org XSL back to reference the correct XPath
  • Fixed improper ServerPath inclusion in fully qualified path assembly – repairs issue with XML and XSL file parse for server side operations when recursive path link is not present

Version 0.91 (released 02 April 2010)

This release includes major performance improvement in transformation and finally allows for XSLT to be performed in the server. These changes were extended to allow the ability to add, edit, and delete records from handheld user agents in addition to providing single record download capabilities as specified file types (vCard now supported for download with a text/x-vcard MIME type)

  • Fixes to eliminate infinite loop in the vertical wrap to ensure IE displays the card view correctly and does not hang. This is related to a change in XSL based rendering in IE, requiring deferal of the wrap function call through a timeout.
  • Introduce session persistence to the LDAP store to offer an alternative to passing credentials in the cookie, replacing content instead with a session id. An additional alternative is also introduced to embed the session id in the URL
  • Introduced server side XSL transformation – integrated into vcard display for the contact records and in general response handling for blackberry user agents.
  • Fixed issue with poor handling of ‘&’ in dn for URL reference to jpegPhoto which was causing some transformations to fail due to incorrect XML parsing
  • Completed the change to DSML response type for jpegPhoto inclusion in the stream to ensure requests from IE return a URL to the photo and not the binary stream while continuing to pass the encoded image to firefox / mozilla based browsers
  • Established uniform page head elements across all pages through introduction of XSL includes and imports
  • Introduced performance improvements by adding indexes in the XSL processing.
  • Introduced first page customizations for handheld user agents – initially only supporting blackberry – to include suppression of JS to wrap columns in the card style. UserAgent parameter added to all xsl templates via the new DSML_sitefrags.xsl inclusion. Telephone dialing, emailing, and SMS functional within handheld devices and tested on the blackberry.
  • Addition of xmlObjectTemplate parameter to ldapupdate handler and the Present action type to present XML documents directly from the server. Formerly, this was achieved by getting XML documents directly via HTTP get requests, but this did not accomodate agents – such as handheld or mobile phone browsers – that did not perform the transform via XSL.
  • Addition of the dlFilename parameter to ldap update handler to allow responses to be provided with an attachment disposition whose filename correlates to the value of the parameter.
