Dug a little more. Seems that ghc 7.4.* finalizes (ldap_unbind action) the ldap ptr before the references were actually dropped.

Re: [Haskell-cafe] What is the difference between runhaskell and compile?
OK. Finally this problem totally prevents my project from working. By some guy's suggestion, I did a packet capturing, which really showed a difference. The rwdc file is for a ldap that at our IDC, which did not work with compiled binary. The rodc file is for a ldap that at local, which worked all the time. Each file contains two parts of records, at 3.* sec and 6/7.* sec. The 3.* part is for runhaskell way. The 6/7.* part is for compiled binary way. The big difference here is: the failed one sent unbindRequest before got bindResponse success.

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.

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.

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.

Alright, with another box of different version of ghc and things. I finally got the cause.

Maybe try with "ghc --make -O0". Afaik, ghci and runhaskell don't do any optimization, which could be the difference.

Re: [Haskell-cafe] What is the difference between runhaskell and compile?
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?)

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.)

Re: [Haskell-cafe] What is the difference between runhaskell and compile?
Versions:
libldap2 2.4.28
LDAP 0.6.6
ghc 7.4.1
Code below:
import LDAP
main :: IO ()
main = do
let domain = "vancloa.cn"
bindDN = "CN=wangshida.admin,OU=admin_accounts,DC=vancloa,DC=cn"
bindPW = ""
baseDN = Just "DC=vancloa,DC=cn"
ldapFilter = Just ("(&(sAMAccountName=" ++ alias ++
")(&(objectClass=user)(!(ou=Recycle_Bin")
ldap <- ldapInit domain ldapPort
ldapSimpleBind ldap bindDN bindPW
And ghc -threaded does not help.

If it is simple then please paste it somewhere. Perhaps stackoverflow
would be a better medium for this discussion.

Re: [Haskell-cafe] What is the difference between runhaskell and compile?
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.

Re: [Haskell-cafe] What is the difference between runhaskell and compile?
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.
