Bug ID: 51274
           Summary: adsldp:ldap crashes in Wine when LDAP has been
                    configured on Linux
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

adsldp:ldap crashes in Wine on cw-rx460 and cw-gtx560. The reason it crashes on
these boxes and not others is that they use LDAP for the user accounts.

0x80072030 is ERROR_DS_NO_SUCH_OBJECT so it seems likely that the crash happens
on the IDirectorySearch_GetNextColumnName() that follows line 391:

390     hr = IDirectorySearch_ExecuteSearch(ds, (WCHAR *)L"(objectClass=*)",
NULL, ~0, &sh);
391     ok(hr == S_OK, "got %#x\n", hr);
...
 400     while (IDirectorySearch_GetNextRow(ds, sh) != S_ADS_NOMORE_ROWS)

This remains to be confirmed however.
Also it may be that this failure is unexpected and just the symptom of some
configuration issue.
