Server :: LDAP Temporary Lookup Failure When Querying From Postfix
Jul 23, 2011
I configured POSTFIX with DOVECOT, LDAP & Squirrel mail on RHEL 5.5. Iam able to login using LDAP authentication. Now i want to deliver mails locally using LDAP. I configured to query LDAP using transport lookup table (ie.transport_maps=ldap:ldaptransport). it shows the following errors:
warning:dict_ldap_lookup:ldaptransport : search base not found-no such object..
Temporary lookup failure.
ldaptransport Configuration:
server_host=hostname of server
[code]....
(But same search_base is configure in Dovecot, it is authenticating) I have searched in net, they are telling that some ASCII encoding problem in postfix to LDAP.

So, I have mail server ( posfix ) and ldap server, they works fine. I can add/delete users from posfix, and they can send / receive mails to/from any address. At same time my ldap server works fine, I have also users in it, my "simple" question would be...if I have user "test1" in ldap, what I have to do to connect--enable that user to send mails ?

Think I've pretty much followed the instructions correctly here.

Also, I looked for the PID of the smtpd and did a strace on it.

However, when I looked at the permission of this file, it should be accessible by everyone.

It seems my laptop (an Acer Aspire One AOA150) runs out of MTRRs at boot. I've done some googling on the problem and read that people recommend turning on MTRR sanitizing to fix it, however, it still occurs. I'm running Arch Linux (but that shouldn't matter). You can see that I have enabled MTRR sanitization here:
[chris@helios ~]$ zgrep 'SANITIZER' /proc/config.gz
CONFIG_MTRR_SANITIZER=y
CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1
CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1
Here is my relevant system info:

I setup Postfix on my Ubuntu 10.04 LTS server but I am getting an error saying: Code: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 SMTP authentication is required. (state 14).

we have a weird problem with our opensuse 11.2 server installation.
We want to set up a LDAP Server using the Yast-LDAP Server configuriation tool.
This indeed already worked weeks ago until....this week.
Maybe some updates??!
I do not know what happend exactly. The server just does not want to start again and throws following error:
Starting ldap-serverstartproc: exit status of parent of /usr/lib/openldap/slapd: 1 failed
This happend after a little check of the configuration, but without a change, with Yast. Google delivered only "reinstall your box"-answers.
So.. i did that. And now the "mystical" part: The SAME ERROR occurs with a fresh vanilla system with a brand new and simple configuration (certificats, database, pw...the first Yast config dialog...). I did not change the way i set it up.
I remember, when i did this the first time with 11.2 on that machine, when no problems occured...everything was running out of the box (except the "use commen server certificate" option...).

The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

I'm trying to integrate sendmail and openLDAP together. I've followed the guide in O'Reilly's LDAP book and my lookups are good. I think my problem is virtual users. What I'm trying to accomplish is that if an email is sent to joe@host.tld and there is an entry in LDAP for joe then it'll be accepted. Right now, it'll only accept emails only for system users. Below is my sendmail.mc (most comments removed)
Code:
divert(-1)dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')dnl
VERSIONID(`setup for linux')dnl
OSTYPE(`linux')dnl
dnl ## I have a real one
define(`SMART_HOST', `my.smart.host')dnl
dnl #
define(`confDEF_USER_ID', ``8:12'')dnl

I am using RackMonkey to map out my lab. Unfortunately, due to RM limitations, every user who accesses the site has write access UNLESS they are logged in as a user named "guest". I currently have Apache allowing only the users (sysadmins) in an LDAP group access to RM, but I would like to allow read-only access for other users as well.I found mod_authn_anon, but I am having trouble combining the two authentication methods. I am using Apache 2.2.18 (compiled myself) on SLES 11.1.
This is the common part:
Code:
AuthType Basic
AuthBasicProvider ldap anon
Order allow,deny
Allow from all
This part by itself works for the LDAP authentication:
Code:
AuthName "System Admins"
AuthLDAPURL "ldaps://example.com/ou=ldap,o=example.com?mail" SSL
Require ldap-group cn=SysAdmins,ou=memberlist,ou=groups,o=example.com
This part works by itself for guest access:
Code:
Anonymous guest
Anonymous_VerifyEmail Off
Anonymous_MustGiveEmail Off
Anonymous_LogEmail on
Require valid-user
But if I have both of the previous blocks enabled at once, then guest access does not work. If I throw in a "Satisfy any", then I am not prompted for a username at all. How can I allow access to this LDAP group and to a user named "guest", but not allow all valid LDAP users to log in?

I'm trying to set up a Linux server and I am new to this. I have gone through most of the configuration using SAMBA 3.0 and when I populate the ldap directory all I get this error before the password request:
Then when I perform an ldapsearch to see if the directory is populated I get this message:
I'm positive all my .conf files are done right.

I'm checking with a sniffer and there's activity going on between the client and the LDAP server... as a matter of fact, the sniffer shows that the search is producing one ldap item, however, php says it can't contact the ldap server (after it has bound and everything):
The script is working beautifully on another host with debian.

Slackware 13 64 - full installation
Postfix from slackbuilds dot org
Dovecot from same
has anyone recompiled Postfix using the Slackbuild script, modifying the script to include support for Cyrus-SASL, OpenLDAP, and MySQL in the build, while retaining Dovecot SASL and TLS? If so I would appreciate it if they could post the CCARGS and AUXLIBS commands. I am having some difficulty getting this working.

In the past I found some great help on this forum, so here goes. Bare with me because it's a long story. I'll try to be as complete as possible. I've installed and configured OpenLdap on a virtual machine with ip 192.168.39.134. I've added 2 users via LAM. In the ou WikiUsers and the domain is wiki.local.
I've then created another host with ip 192.168.39.133 with mediawiki installed on it. Then I added the extension LDAPAuthenthication. In the LdapAuthentication file I added this code (only the last paragraph is mine, I added the others to show it's location in the script):
Quote:
$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );
[code]...
I know I'm close because I can't register any new users or accounts on the mediawiki site. Although I could before I added the LDAP service. This is indeed all just to test and get to know how LDAP works. That's why it's all virtual in VMWare. I did not really configure anything on the LDAP, i just installed it and chose a domain (wiki.local).

so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied
I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.

I'm trying to configure postfix on an ubuntu virtual machine to use gmail as a relay client. For the past two days I have been in and out of the logs, changing parameters and blindly following tutorials but I can't get anything to work properly. So far I've narrowed my problems down to tls connection establishing and a failure to authenticate, judging by the local emails I've received from "The mail system".

can anyone tell me what is the difference between these two files of LDAP client /etc/ldap.conf and /etc/ldap/ldap.conf and for what purposes these two files gives services. Is it necessary to have these two files at a time ?
I use these files to install LDAP client to authenticate with our LDAP server by creating a symbolic link of /etc/ldap.conf to /etc/ldap/ldap.conf.
