Fedora directory users - Jul 2009 - [389-users] Getent and ldapsearch import from openldap

Hi all,

I am trying to migrate all users from openldap to FDS. The schema and object
class in openldap is pretty messed up and needs lot of massaging. I tried
exporting the schema and running the conversion script but it usually fails
and the db import is not correct.

Requirement: Only users with uid, gid and homedir needed. Nothing more or
less

So I did this, for Users, uid, gid, homedir import:

#getent passwd
Sample output:
oracle:x:1001:1001:oracle:/home/oracle:/bin/bash

Now, run  ./migrate_passwd.pl on the aboveoutput to convert to ldif file.
The result was like below.
Sample output ldif:
dn: uid=oracle,ou=People,dc=fedorads,dc=net uid: oracle cn: oracle
objectClass: account objectClass: posixAccount objectClass: top
userPassword: {crypt}x loginShell: /bin/bash uidNumber: 1001 gidNumber: 1001
homeDirectory: /home/oracle gecos: oracle

For Password import

ldapsearch ­D BindDN ­W ­x uid=* userPassword uidNumber gidNumber
 sample
dn: uid=oracle,ou=People,dc=padl,dc=net uidNumber: 1001 gidNumber: 1001
userPassword:: e01ENX1nbDdQNm5iU3FQOGZJOTdVWXM2QXp3PT8H9

Question 1: Please comment on above. Tell me if I could have simplified the
approach. Is there a better way to import the password from OpenLDAP? The
conversion schema is not working for me and it was set default.

Question 2: Now I have two database with user and password separate. Can I
import them separately and have it working?

Question 3: When I imported, I got only 500users in db and rest didn¹t make
it. I am trying to remember which file and what limit needs to be edited for
this issue.

Q1 - yes
Q2 - no
Q3 - yes, I think the rootbinddn does not have limits in openLDAP

ldapsearch -D BindDN -W -x ''(homedir=/home/*)'' -l max >
/tmp/dump.ldif

but definitely use rootbinddn so you get passwords and no limits
