Hi, I am writing a small program using LDAP hackage. A weird problem occured. When the code was run by runhaskell, things were fine, worked as expected. But when ghc compiled (no any args), and ran, I got this: LDAP error: ldapSimpleBind: LDAPException LdapServerDown(-1): Can't contact LDAP server. There is sure no problem with the server. So I am confused. I thought the two supposed to be the same. -- 竹密岂妨流水过山高哪阻野云飞 And for G+, please use magiclouds#gmail.com.

Can you paste your code somewhere? I'm using the LDAP package at work (for authenticating a Yesod app) and a quick test of the basic LDAP package in GHCi works for me: λ> import LDAP λ> ldap <- ldapInit "10.0.0.12" ldapPort λ> ldapSimpleBind ldap "geva" "**********" λ> let desiredAttr = LDAPAttrList ["name"] λ> let searchDN = Just "OU=Redacted,DC=redacted,DC=com" λ> let searchFilter = Just "sAMAccountName=geva" λ> ldapSearch ldap searchDN LdapScopeSubtree searchFilter desiredAttr False [LDAPEntry {ledn = "CN=Vincent Ambo,OU=Redacted,DC=redacted,DC=com", leattrs = [("name",["Vincent Ambo"])]}] It also works in compiled applications and in source files run with runhaskell. Our directory server runs Active Directory. On May 24, 2012, at 11:36 AM, Magicloud Magiclouds wrote:

Hi there, The code could not be simpler. Just ldapInit, ldapSimpleBind. I just found that the code works with ghci, too. So to sum up, ghci/runhaskell works, ghc not. On Thu, May 24, 2012 at 8:15 PM, Vincent Ambo wrote:

New subject: What is the difference between runhaskell and compile?

I have been using LDAP with GHC without a problem – I get this error often but the problems have been with the configuration of the OpenLDAP client library or the OpenLDAP server. We are all taking about LDAP-0.6.6? Which version of GHC are we talking about? (I don’t think I have tested this on GHC-7.4.1, and maybe the others haven’t either.)

Hi, Sorry for the delayed reply. I am using ghc 7.4.1 and LDAP 0.6.6. When you said "configuration of the OpenLDAP client library", may I have more information? Since ldap-utils and other client (php, perl, etc) do not have any problem. This might be the only clue to me. On Fri, May 25, 2012 at 4:43 PM, Chris Dornan wrote:

By configuration of the OpenLDAP client library I mean mostly so that SSL connections will work, but this is all system-level configuration. That GHC establishes connections in interactive mode for you indicates that the problem is not with the LDAP systems, but that something peculiar is going wrong with your GHC installation. Do you have only the one GHC installation on the system; is there any chance that ghc and ghci could be selecting different installations? Is it easy for you to try connecting with GHC-7.0.4? It would be worth a try if you can -- it might be a 7.4.1 oddity but it looks as if it could be some kind of GHC mis-installation. (If trying this with GHC-7.0.4 would be bothersome I would be interested to hear more; which O/S are you using?)

Alright, with another box of different version of ghc and things. I finally got the cause. Or may I say as simple as Ozgun said, ghc 7.4.1 defaultly uses optimization. ghc-7.4.1 -O0 works. ghc-7.2.2 also works. Thank you all. On Sun, May 27, 2012 at 7:07 PM, Chris Dornan wrote:

It sounds like this should be looked at further. Somebody should verify try to repeat what you are seeing on 7.4.1. The release candidate for 7.4.2 should also be tried. (I will see if I can get time to do it myself.) Chris

I have set up this test on 7.4.1 and I cannot recreate the problem -- compiling and running an equivalent program (the posted program with local domain, bindDN and bindPW definitions localised and all other let bindings removed) leads to a successful server connection when passed the right password but fails to connect with the wrong password. This was the behaviour you were seeing yourself with 7.2.2 was it not? I can only recommend re-installing 7.4.1 and trying again. Chris

Interesting. I have this code tested in Debian unstable/stable, CentOS 6.1, all 64 bit, with two different version of libldap2. At first, Debian-s were installed with 7.4.1, CentOS with 7.2.2. Only in CentOS the code connected after compiled. Then I removed 7.4.1 from Debian stable and installed 7.2.2. The code worked. At last, I installed 7.4.1 in CentOS. The code did not work. Could you send the .hi/.o to me, so maybe I could find out the different? Also the exact original source. Thank you. On Mon, May 28, 2012 at 6:27 PM, Chris Dornan wrote:

Interesting indeed! I am guessing that you are using the GHC-7.4.1 bindist from haskell.org. I will try and find some time to marshal the source code and intermediate files (am on the road -- will need to collect it from base, make it generic etc.). You might also like to try the http://justhub.org ghc-7.4.1-hub on your CentOS-6.1 node. It is a separate build from the haskell.org bindist and comes with it's own in-board gcc (4.6.1) and binutils (2.21) used for the build. It should work for you.

Hi there, The code could not be simpler. Just ldapInit, ldapSimpleBind. I just found that the code works with ghci, too. So to sum up, ghci/runhaskell works, ghc not.

A possibility that occurs to me: does it by any chance work with ghc -threaded? Perhaps the issue relates to the different behavior of the threaded runtime (which is used automatically by ghci/runghc).
