Can you try with valgrind? It will slow down the logins a bit though.

Hello list, I am struggling with setting up dovecot 2.1.7 with samba 4.1.2 on debian wheezy. Dovecot should authenticate via LDAP, but I?cannot get it to work reliably. Sometimes auth works, sometimes not. Referals are already activated in ldap.conf ? LDAP-authentication works fine with other clients (Apache Directory Studio, ?)? Has somebody got a similar setup running? I would love some hints on how to debug...

Hi ! Yes it happens every 2 to 5 minutes so no problem in reproducing. I made the change with valgrind, I have now this in my log : Dec 4 12:00:27 xxxxx dovecot: auth-worker: Error: ==2436== Invalid read of size 8 Dec 4 12:00:27 xxxxx dovecot: auth-worker: Error: ==2393== Invalid read of size 8 Dec 4 12:00:27 xxxxx dovecot: auth-worker: Error: ==2476== Invalid read of size 8 Dec 4 12:00:27

Hello List, This is dovecot 1.0.0 on FreeBSD 4.11-STABLE. I did not provide this information before:-) I am back again and I think I am edging closer to getting a solution. I have done some modifications and now dovecot gives me a different error message than before.... Here is what I have for the password_query and user_query password_query = SELECT popbox.cleartext AS password FROM

Hello, I am running a Dovecot server (version 1.2.17) on FreeBSD 8.2, using LDAP to authenticate Active Directory users. I can successfully bind and authenticate using PLAIN and LDAP without SASL, but obviously passwords for the bind user and the user being authenticated are being passed in plain text. I've attempted to configure my server to us SASL however when I attempt to auth...

Hello Timo, We have installed dovecot 2.0.10. With LDAP authentication. Users authenticate successfully but in the authentication process there are errors that I don't understand because it's everything all right: May 10 18:00:49 carpe3 dovecot: auth: Error: ldap_unbind May 10 18:00:49 carpe3 dovecot: auth: Error: ldap_free_connection 1 1 May 10 18:0...

We have been running Samba 2.2.x for some time without problems. Servers are Solaris 2.7 and RH Linux. Clients are a mix of WinNTsp4 and Win2K. Server setting is for plaintext (un-encryted passwords). On upgrading the Samba server to 3.0.0, (smb.conf file unchanged): All WinNt clients fail to authenticare. Win2k clients authenticate correctly. On reverting back to Samba 2.2.x, all cleints authenticate correctly. The same symptoms are obseved, independent of wheter the underlying OS is Solaris 2.7 or Linux. Below is level 10 traces of 1. WinNT system [bilbo] failing to connect to server [yo...

I hope that someone will be so kind to help me into solving this really strange thing (don't know if it is a bug or not) I have a samba4 server and want to use postfix+dovecot - dovecot version is 2.0.11 as for the postfix side everything is OK (all the LDAP lookups works without any error, tested also manually with postmap -q) the real pain is with dovecot deliver: it seems that

Hi, I think the error is in converting the POSIx ACl, but I don't know how to fix this.
