Topic: Migrate all accounts to new server

Hi, I need help. I need to migrate whole iredmail with iredadmin pro from old server to new one. I installed fresh debian squeeze server with fresh installation of iredmail and iredadmin ldap pro. But when I want to migrate ldap from old server, i ged this errors:

==================================================================================
Could not add the object to the LDAP server.
LDAP said: Constraint violation
Error number: 0x13 (LDAP_CONSTRAINT_VIOLATION)
Description: Some constraint would be violated by performing the action. This can happen when you try to add a second value to a single-valued attribute, for example.

LDIF text import
Could not add object domainname=domena.cz,o=domains,dc=xxx,dc=cz
LDAP said: Constraint violation
Error number: 0x13 (LDAP_CONSTRAINT_VIOLATION)
Description: Some constraint would be violated by performing the action. This can happen when you try to add a second value to a single-valued attribute, for example.

=========================================================================================================

So nothing was imported. I followed this help: http://www.iredmail.org/wiki/index.php? … ail.Server

Maybe I made mistake by removing lines from ldif file? Which lines must I remove? Other steps are ok, but ldap can get to work. Can anyone help me?

- Was there any error while import import LDIF data with slapadd?
- Any error log in Apache log file of "Internal server error"?

P.S. I just realized i missed another step after restoring LDIF data, here it is:

IMPORTANT NOTE:

If you're restoring LDIF data (exported on an old iRedMail server) to a new
iRedMail server, you MUST login to phpLDAPadmin and reset passwords of
below two DNs. Because they're hard-coded in many config files. For example,
/etc/postfix/ldap/*.cf, /etc/dovecot/dovecot-ldap.conf.

    cn=vmail,dc=xxx,dc=xxx
    cn=vmailadmin,dc=xxx,dc=xxx 

The new passwords you should use can be found in the root directory of
iRedMail installation directory, for example, /root/iRedMail-0.7.4/iRedMail.tips.
Below is the sample of the passwords in file iRedMail.tips:

-------------
# File: iRedMail.tips

OpenLDAP:
    ...
    * LDAP bind dn (read-only): cn=vmail,dc=example,dc=com, password: py2BQwM0zoRM5nciK68AlP8dyu2Mq6               
    * LDAP admin dn (used for iRedAdmin): cn=vmailadmin,dc=example,dc=com, password: 9wr0mHeVYz2uaxSAGBLucVkOgYPSBB
-------------

Please login to phpLDAPadmin and reset passwords.

It's updated in wiki tutorial also:
http://www.iredmail.org/wiki/index.php? … FAQ/Backup

So sorry about my mistake.

Hi, thanks.

You wrote "If you're restoring LDIF data (exported on an old iRedMail server) to a new
iRedMail server, you MUST login to phpLDAPadmin and reset passwords of
below two DNs." - you mean on the new server?

This is my apache error log:

Yes. (Sorry about the confusion, fixed in wiki tutorial.)

INVALID_CREDENTIALS always means you're using an incorrect bind dn and/or password.

1) Make sure OpenLDAP is running
2) Make sure you're using correct bind dn and password.

Re: Migrate all accounts to new server

Hi, but I log in with the same password and dn, as before ldif import. Is it possible, that is any problem with openldap? For example when I want to stop this service it didnt stopped and this is problem?

You can use command 'ps' to verify whether it's stopped or not. For example:

# ps aux | grep ldap
# ps aux | grep slapd

Re: Migrate all accounts to new server

Hi, I am sorry, but I can get it! I followed your howto step by step, but I can not get it work.

1. I export data on an old server with your ldap backup script, than I copy ldif on new server
2. I stop slapd, delete all files except DB_CONFIG
3. I imported data from ldif file
4. I start slapd - but I dont get the error messages which you wrote at howto
5. Here comes the problem, I can not login to phpldapadmin, it tells me, that can not connect, so I can not reset the passwords

Is it possible, that you make one script which can make the whole process of migrate datas???
I need to migrate datas, but now it is already 2 - 3 month of my attempts to migrate datas. It is for me really important....
