I have a bad memory, and need a to-do list. If I have promised to add something for you in the next version, and it isn't in the list below, please add it.
Fix referencs to $ldapconn that should be $this->ldapconn in primary group code for AD(in SVN)
- Fix User not loaded from session issue 
- Change behavior of locally managed groups to allow MediaWiki specific groups to be overridden 
- Fix the username-authentication issue once and for all (hopefully without nasty hacks)  
- Fix the issue where local users can't change their passwords 
- Add strictUserAuth support
- Add support for automatic domain discovery
- Refactor the code to handle configuration globals differently
- Add an option for schema type, so that common options can be automatically configured
- Fallback to defaults when certain options aren't set
Fix memberOf with memberOf overlays(in SVN) 
- Add check for non-returned data 
- Add $wgLDAPAllowLocalUsers and $wgLDAPRequiredUsers as a way to allow a list of local users (e.g., WikiSysop) and a list of LDAP users for access. 
- Ensure compatibility with PHP 5.3 
- Fix issue with excluded groups 
- Support dynamic groups 
Possibly in a future versionEdit
- Allow changes to LDAP groups via Special:Userrights
- Support for choosing default search scope, and defining it for multiple domains.
- Support for adding users/changing passwords in Active Directory.
- Support for using LDAP as a complete user backend (including user options and such). Using ldap as a backend will require a custom schema to be loaded in the LDAP server.
- Optionally munge usernames when using auto-auth
