Only bind user can connect to Postfix server using LDAP

I have a functioning Active Directory server, but whenever I try to authenticate against the Postfix server that uses it (with saslauthd) I notice that only the bind user can connect. Whenever I try to connect to the server with valid credentials, it does not work.



Any idea as to where I can debug why only the bind user can log in?
I know it's possible, because I have another setup with Postfix authenticating against LDAP with all users, but I cannot seem to figure out what the difference is between those.

          Shortly after posting this question, I found the answer myself.



          The problem was that my ldap_search_base had the bind user cn=postfix in /etc/saslauthd.conf. After changing the search base to the Users OU, it started to work :)

                    How many registers does an x86_64 CPU actually have?

                    Image
                    Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
