Migration guide from Zentyal 2.2 to Zentyal 3.0 published!
« on: December 27, 2012, 12:25:47 pm »
Hi Zentyal 2.2 users,

We know that many of you were expecting a way to migrate your configuration from a Zentyal 2.2 to the new Zentyal 3.0 server and we're glad to let you know that a migration guide has now been published!

It is important note that due to the mayor changes introduced in Zentyal 3.0 (new distribution base, Kerberos, deep changes in some modules like HTTP Proxy, etc.), migrating everything is not possible. However, the migration guide provides some helpers to ease the migration process and helps to avoid manual configuration from the scratch.

You can find all the information at:

http://trac.zentyal.org/wiki/Documentation/Community/Migrate_2.2_to_3.0

If you are missing some specific information, please do request it through the Forum and we'll do our best to include it. When additional migration information is available, it will be documented on this same page.

We hope you will soon enjoy your new Zentyal 3.0!

A huge "thank you"!
I find this configuration export much safer than the previous migration tool. This wil yield cleaner results.

Cheers.

Hi,

Thanks for the scripts.

Is it also possible to upgrade from release 1.4.9 ?
I suppose that there are changes needed then because teh home structure of 1.4.9 is not the sam as in 2.2.

Only importing the users and groups is al a great advance.

Thanks and best regards,
Ian

Nice, but can't migrate passwords? Unless your deployment is trivial that's a pretty big deal. I would think one could copy over the hashes manually.

http://lists.samba.org/archive/samba-technical/2012-June/084758.html

Quote
The unicodePwd appears to be same hash as for sambaNTPassword in
samba3 ldap just using base 64 encoding rather than direct hex
printing of the value previously.

So copy the Samba NT password to the samba 4 ldap schema then copy userPassword for plain old ldap. Has anyone tried this? Am I missing something? I'll see if I can do this next week.

Of course if LM passwords are enabled (which is default) you can just use rainbow tables, yay security. Sadly I don't have LM passwords for all my users.

I had a bout with the flu so am just now trying this.  In your documentation you say:
sudo perl dump-users-from-backup confbackupname.tar users.csv
Did you mean?
sudo perl dump-users-from-backup confbackupname.tar >users.csv

Ok so LDAP password migration is not so bad. This doesn't include Samba!

1. In your 2.2 ldap server you need to get the userPassword attributes for all users. You can find gui tools or do cli like:
ldapsearch -D 'cn=ebox,dc=domain,dc=org' -w 'password_from_ldap_settings' -b 'dc=domain,dc=org'
That dumps out everything but what you want is the uid and userPassword. Keep in mind userPassword is a base64 of the hash.

2. Import your users as the guide suggests. Now they have bad passwords.

3. Decode passwords like this

echo crazy_base64_thing_you_got_from_ldapsearch | base64 -d

This decodes it but it's still a hash. It should start with something like {SHA} but could be some other type of hash depending on your setup.

4. Use ldapmodify on the 3.0 server to set the userPassword. By default the userPassword is just a base64 of {K5KEY} which isn't the password at all. I'm guessing it just saying use kerberos?
To do this make a ldif file like

dn: uid=username_here,ou=Users,dc=domain
changetype: modify
replace: userPassword
userPassword: {SHA}fdslfjdsffljsdfljsdfll

where userPassword is what you did base64 -d to. Run it like

ldapmodify -D 'cn=zentyal,dc=domain' -w 'password_from_ldap_settings' -p 390 -h yourhostname -f your_file.ldif

Verify it worked by running the ldapsearch command like you did in 2.2.

Now users can log into User's Corner, use pam_ldap, any other systems that depend on the ldap auth backend. In User's Corner people could change their own passwords and it updates everything! But this still sucks and forcing all employees to reset passwords is a great way to make people hate you.

I'll play with Samba and report back. Maybe I'll even make a script.

Ok samba guide. This does not include kerberos just basic samba authentication. Please note this is a proof of concept, I haven't tried this in production and neither should you without sufficient testing.

Get a list of uid and SambaNTPassword from Zentyal 2.2 as described in the above ldap guide.

I used python since we need to manipulate the hash a bit. Execute this on the 3.0 server. Fill in the username, password, and domain of course

Code: [Select]
import base64
import binascii
import subprocess

sam_file = "/var/lib/samba/private/sam.ldb.d/DC\=DOMAIN.ldb"
user_dn = "CN=<username goes here>,CN=Users,DC=domain"
ldap_samba_nt_password = "<SambaNTPassword goes here>"
b64_hash = base64.b64encode(binascii.a2b_hex(ldap_samba_nt_password))

cmd = """ldbmodify -H %s --controls=local_oid:1.3.6.1.4.1.7165.4.3.12:0 <<EOF
dn: %s
changetype: modify
replace: unicodePwd
unicodePwd:: %s
EOF""" % (sam_file, user_dn, b64_hash)
subprocess.call(cmd, shell=True)

You can test with smbclient.

I'll probably improve the script to handle a big list of users and passwords. Is there any reason this isn't a good migration strategy? If users weren't using kerberos before, why would they miss it with 3.0? And if they want it they can just change their password at their leisure.

A Linux client with pam_ldap who is mounting samba shares should never notice the change (in theory). I'm less sure about Windows clients, will they attempt to use kerberos and then fail?

See my question above.  My question was actually a gentle "fix the documentation" type question.  They left out the > in the command.

Code: [Select]
sudo perl dump-users-from-backup confbackupname.tar >users.csv

Thank you, that resulted at least in a users.csv, though the errormessages stay the same.

The "only" remaining problem is, that import-basic-modules seems not to do what I expected it to...
Or is it not its job to configure file sharing, shares and printers with their access rights?

I am sorry,  it has been too long since I ran the upgrade to remember which modules it carried over but you will have to do significant re-work in the file sharing module for sure.  Wish I had better news but I can see where writing an upgrade tool would have been a huge effort in the samba module.

folks, this is ridiculous. Migration needs to be part of the plan, not something you stick on after.

What about Zarafa for instance? Yes I can migrate emails via IMAP client if need be (gee, thanks), what about address books and calendar info? And no upgrade-in-place? Disappointed I am. If you are planning to do better than the competition, you need to do better than the competition. :(

This is not a migration!

Yea I'm still trying to plan my migration. Their old desktop debian package would set up pam_ldap for you but in 3.0 it's not compatible because they changed the ldap port, restricted anon searching, and do groups in a very different schema. So even if I redid the entire zentyal server I would have to change each and every client too. I'm no longer recommending Zentyal as a reasonable alternative to AD though. Hope to have a real migration guide for you all soon. I don't use Zarafa though so you are on your own with that. Good to know I should never consider it.
