How to import ldif users into FreeIPA?

  • 772

Maybe it needs two steps:

  1. Add users defined in the ldif file to OpenLDAP(Inside FreeIPA)
  2. Migrate those added users from OpenLDAP to IPA

Current situation

Setup FreeIPA server, initilized an admin user, created a test user by ipa user-add command.

List all users in IPA

# ipa user-find --all

Try to add users by ldif file

For first step above

Create a test ldif file

test.ldif

# Add test1
dn: uid=test1,dc=my,dc=domain
changetype: add
objectClass: inetOrgPerson
description: Test1
  d
  e
cn: Test 1
sn: Test
uid: test1

# Add test2
dn: uid=test2,dc=my,dc=domain
changetype: add
objectClass: inetOrgPerson
description: Test2
  d
  e
cn: Test 2
sn: Test
uid: test2

Add them

# ldapadd -x -h test.my.domain -D "cn=Directory Manager" -w password -c -f test.ldif

Check them

# ldapsearch -h test.my.domain -t -b "dc=my,dc=domain" "uid=test1"
SASL/GSSAPI authentication started
SASL username: [email protected]
SASL SSF: 256
SASL data security layer installed.
# extended LDIF
#
# LDAPv3
# base <dc=my,dc=domain> with scope subtree
# filter: uid=test1
# requesting: ALL
#

# test1, my.domain
dn: uid=test1,dc=my,dc=domain
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
description: Test1 d e
cn: Test 1
sn: Test
uid: test1

# search result
search: 4
result: 0 Success

# numResponses: 2
# numEntries: 1

# ldapsearch -h test.my.domain -t -b "dc=my,dc=domain" "uid=test2"
SASL/GSSAPI authentication started
SASL username: [email protected]
SASL SSF: 256
SASL data security layer installed.
# extended LDIF
#
# LDAPv3
# base <dc=my,dc=domain> with scope subtree
# filter: uid=test2
# requesting: ALL
#

# test2, my.domain
dn: uid=test2,dc=my,dc=domain
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
description: Test2 d e
cn: Test 2
sn: Test
uid: test2

# search result
search: 4
result: 0 Success

# numResponses: 2
# numEntries: 1

They are there.

For second step

# ipa migrate-ds ldap://test.my.domain:389 --with-compat
ipa: ERROR: user LDAP search did not return any result (search base: ou=people,dc=my,dc=domain, objectclass: person)

Checked FreeIPA dashboard, no new users(test1, test2) there. How to migrate?

  1. I'm in a similar boat at the moment. As far as I understand, FreeIPA requires some specific objectClasses and attributes present in LDAP entity for it to be aware of those entities. As far as I've figured, those seem to be at least: "objectClass: ipaobject" and "ipaUniqueID". Lacking these required attributes, users will not show up in IPA, but will be accessible via direct LDAP.

    First of - normally FreeIPA users are stored under cn=users,cn=accounts, such as

    dn: uid=ipa_test9,cn=users,cn=accounts,dc=myserver,dc=eu

    As for why ds-migrate didn't find users - your users currently are under

    dn: uid=test2,dc=my,dc=domain

    while ds-migrate looks for users in yet another place

    (search base: ou=people,dc=my,dc=domain, objectclass: person)

    For migrate-ds to work at all, you'll have to specify at least --user-container parameter. After hacking migrate.py file to autogenerate missing groups, I tried with

    $ ipa migrate-ds ldaps://im.myserver.eu --bind-dn="uid=myuser,cn=users,cn=accounts,dc=myserver,dc=eu" --with-compat --user-container="cn=users,cn=accounts,dc=myserverdc=eu" --group-container="cn=groups,cn=accounts,dc=myserver,dc=eu"

    and it reports that all the users already exist. Since FreeIPA uses the same LDAP as the one you are trying to "migrate from", it detects that UIDs are already there and there's nothing to migrate.

    Basically, a workaround would be to set up another temporary LDAP server, import users into that, then use migrate-ds against it.

    EDIT I did it this way and it worked. You still have to reset passwords and create Kerberos tickets, so my conclusion is that it's much easier and quicker to write a little python/bash script that creates users, generates password and emails it to user with instructions on how to update.
