When trying to open Active Directory User and Computer tool in a Windows 2008 server that is part of a Samba4 domain I had the error : "directory property cannot be found in the cache" I got it with the lastest samba4 commit and even with wspp-schema branch.
After some investigation I came to the conclusion that Windows 2008 is expecting this attribute in the rootDSE :SupportedCapabilities. Adding this attribute directly into the sam.ldb file had prouved to be enought to solve the problem. This attribute should have at least this value: 1.2.840.113556.1.4.800 But as Samba4 is capable we can add this value: 1.2.840.113556.1.4.1791 In this email I made the description of those OID: http://lists.samba.org/archive/samba-technical/2009-March/063891.html
Created attachment 4279 [details] Proposed patch for implementing supportedCapbilites in rootdse
Good, that should be fixed! Thanks for reporting this.
