Hello all,


I'm migrating our OpenLDAP-based IdM-system to IPA. Instead of using
migrate-ds I used some custom scripts to import all of our users (~250)
and groups (~85) with IPA commands (ipa user-add etc.). To move
passwords I configured the ipa-server to run in migration mode and did
an ldapmodify like this:

    dn: uid=jitse,cn=users,cn=accounts,dc=domain,dc=nl
    changetype: modify
    replace: userPassword
    userPassword: {SHA}hash

Logging in to a machine running CentOS and ipa-client for the first time
works like a charm, a krbPrincipalKey is generated and Kerberos 'just'
works. However, logging in to Fedora 20 for the first time throws a
'permission denied'. Logging in to Fedora works after logging in to
CentOS or the IPA migration web ui.

Both CentOS and Fedora are fully up-to-date using only the base
repos. Config of the clients is done with ipa-client-install.


Could you attach log files with debug_level 9?

LS


Sure. Just sssd_domain or do you need more?

Are you using two different ipa servers?
ldap://vm-ipa.domain.nl, ldap://vm-ipa.a-eskwadraat.nl

sssd_domain.nl.log, loglevel 9
Fedora: http://pastebin.centos.org/8291/
Constructed uri 'ldap://vm-ipa.domain.nl'

CentOS: http://pastebin.centos.org/8296/
Constructed uri 'ldap://vm-ipa.a-eskwadraat.nl'

The problem is also present in RHEL7b with
ipa-client-3.3.3-5.el7.x86_64 and sssd-1.11.2-1.el7.x86_64

sssd_domain.nl.log, loglevel 9

Could you also provide krb5_child.log and ldap_child.log from fedora machine?
     (debug_level 9)

LS


No, I'm using only one ipa server (vm-ipa). I accidentally
copy-pasted without changing the domain name ;)

Any chance you could use the migrate-ds script to migrate users? I'm
not 100% sure if your own upgrade method does the same thing..
I don't think so, our old LDAP schema is a mess...

It looks like password is expired for user jitse.

My hands were faster than my mind.

I wanted to wrote:

It is really weird because it works on Centos.
Do you have a synchronized time on all machines with ipa server?

LS

Yes, time is in sync across all machines. I think the most
interesting lines in the log are these:

This is where krb5_child on fedora just stops working while
krb5_child on CentOS does this: http://pastebin.centos.org/8316/


Can you send the krb5_child.log file with the success from CentOS as
well? Looks like we might handle some error codes differently after
introducing the sssd_errors code.

bye,
Sumit

That last pastebin (http://pastebin.centos.org/8316/) was krb5_child.log from a succesful first-time login on centos.

> I'd be curious what the krbPasswordExpiration is for this user.
See http://pastebin.centos.org/8321/ for a password migration and output of ldapsearch.

Output of ldapsearch *after* logging in to CentOS for the first time:
    krbPasswordExpiration: 20140310183603Z
    krbLastPwdChange: 20140310183603Z
