Description Michael Adam 2010-12-30 04:12:24 UTC
In winbind_rpc.c:query_user_list, the return code of rpccli_samr_QueryDisplayInfo() is not properly evaluated
before accessing the disp_info results, which leads to
an error if the rpccli command failed.

Patch follows next...

patch with bugfix for 3.5

Fix that applies to v3-5-test.

This is the way master also does this, but here the fix was
introduced in a refactoring commit c83e8cbe4ae3192b576b47bfae2a4ba90d6e0ce9.

I am not 100% sure that this is correct in all cases
(e.g., what if NT_STATUS_NO_MORE_ENTRIES is returned?
should we pass that on or return NT_STATUS_OK intstead?)
But all my tests were ok with the patch.
