Re: [Freeipa-users] Stale NFS file handle

2012-09-13 Thread Ondrej Valousek

You can get authentication failure if the user's home is on a NFS which is 
failing to re-mount.
The stale NFS handle usually means the NFS server changed fsid of the exported 
volume after its reboot.
This usually happens if you are exporting a LVM partition via NFS.
The workaround is to specify fsid of the exported volume manually in 
/etc/exports

HTH,
Ondrej

Hello,
My ipa server and my nfs server are the same machine running centos 6.3.
The server was accidentally down and rebooted.
But then I got authentication failsure on some clients when tried to log on through gdm, and blue screen (no desktop, no panels) on some 
others.

On some clients that I was on before the server was downthe, I got Stale NFS file 
handle.
Yet on some other clients, everything is fine. All clients are running centos 
6.3, too.
Is there a way (e.g. restarting some services) to get the above problems away 
instead of rebooting the clients?
Thanks,
George

[Freeipa-users] IPA 2.2 and windows clients with MIT kerberos distribution

2012-09-13 Thread Baptiste AGASSE
Hi all,

Some days ago i've said on freeipa IRC channel that the documentation on 
freeipa + apache + SNI (located here 
http://freeipa.org/page/Apache_SNI_With_Kerberos) was wrong. 
I've set up a apache server with SNI and tested sso with mit kerberos on 
windows 7 64bits + firefox . On my windows 7 client, sso don't work if i set 
dummyhost apache virtualhost Krb5KeyTab and KrbServiceName, but works if 
Krb5KeyTab and KrbServiceName are those of real host. This behavior is reversed 
with fedora 17 + firefox client: sso works only if dummyhost apache 
virtualhost Krb5KeyTab and KrbServiceName are those of the dummyhost.

So, the conclusion is: the documentation is good for linux clients (at least on 
fedora 17 + firefox), but not for windows clients

I think it will be good to have the same behavior on linux and windows client 
because it will be painful in cross platform environments if it stay as this.

rcrit said on IRC that you are working on v3 at this time, it will be good to 
know if the v3.0 have the same behavior, but i don't have resources at this 
time to setup another test environment with v3 beta.

Detailed test configuration:

(see attached apache config extract for virtualhost configuration)

IPA server:
OS: CentOS 6.3
IPA: ipa-server.x86_64  2.2.0-16.el6
389 ds: 389-ds-base.x86_64 1.2.10.2-20.el6_3

IPA Realm: EXAMPLE.COM

Apache SNI server:
OS: CentOS 6.3
real hostname: projects.foo.example.com
dummy host 1: svn.example.com
dummy host 2: redmine.example.com
[...]

Windows client:
OS: Windows 7 64Bits.
Browser: Firefox 15.0.1, 14.0.x (32bits)
MIT Kerberos dist: 3.2.2 (32bits) (http://web.mit.edu/kerberos/dist/)

GNU/Linux client:
OS: Fedora 17 x86_64
Browser: Firefox 15 (latest provided by fedora)
Kerberos: (latest provided by fedora)

Have a nice day.

[Freeipa-users] Questions about FreeIPA vs 389DS

2012-09-13 Thread mailing lists
Hello all,

 It is difficult for newcomers to cope with all this 389DS/FreeIPA stuff, after 
reading the project documentation and several mail messages in the archives I 
still have some unanswered questions so I would be very grateful if list 
members could answer the following doubts.

I need use services in an Active Directory environment and the WinSync solution 
has important limitations, the MODRDN operation is not handled correctly losing 
the relation with AD objects (it delete and add the entry so a new SID and GUID 
is assigned), the upcoming IPAv3 Trust feature seems very promising because 
AFAIK no sinchronization is necessary, but by using IPA it seems very 
restrictive to support current applications which need a LDAP hierarchical 
tree, custom schema with custom objectclassess and attributes, custom ACLs for 
applications.. I know about Directory Server virtual views, but I'm worried 
about the consequences of low level manipulation of the FreeIPA Directory 
Server instance. 

So how others are solving this paradox?
they run  389DS with (fractional) replication towards (or from) FreeIPA 389DS?
they add custom schemas to FreeIPA 389DS?
the do low level manipulation of FreeIPA 389DS for ACLs, plugin activation, 
...? 
what about upgrades after this modifications were done?

[Freeipa-users] clients very slow

2012-09-13 Thread David Fitzgerald
Hello Everyone,

I work at a small university and I deployed freeIPA on my Linux network over 
the summer break with no (known) problems,  and everything worked as expected.  
However, now that the semester has started and the Linux system is under a much 
higher load, I am noticing that my client machines will randomly slow to a 
crawl.  For example, I have a lab of 25 machines.  The students can log in ok, 
but after a time, a few of the machines will freeze so that the users on those 
machines cannot do anything.  After a few minutes, the frozen machines will 
unfreeze, but other machines will freeze up.  I can't see any pattern to what 
machines freeze up.  I did not have this problem when running NIS, so I suspect 
it is something in freeIPA but I am not sure what to look for to solve the 
problem.  Probably a setting somewhere needs tweaked but I don't know.  The 
server and clients all run Scientific Linux 6.2.

Can anyone help me troubleshoot this?

Thanks!

Dave

[Freeipa-users] IPA Automount cross-location support

2012-09-13 Thread Sigbjorn Lie
Hi,


I opened a request a while ago for Automount cross-location support.
https://bugzilla.redhat.com/show_bug.cgi?id=768177
https://fedorahosted.org/freeipa/ticket/1699#

I see from the comments that it's uncertain how this can be implemented.

Could the Virtual Views in 389-ds be used to implement this the cross location 
maps?

I'm picturing the ability to add a virtual automount map to an automount 
location, where you
select an existing map from one of the other automount locations to display.

All changes to the map will be done in the original map in it's orignal 
automount location, but it
will be displayed in both automount locations.

Any thoughts to that solution?

Siggi

He wants to be able to share a common set of maps between locations 
rather than having to duplicate them across each location.


We're limited by the LDAP clients at this point because they just query 
a basedn and can't really do anything complex.


Using a virtual view is one of the options we've considered, but 
honestly we haven't spent a lot of time looking into this yet. The 
problem with trying to virtually add things to a location is it could 
get very complex very quickly and either hamper performance, debugging, 
or both very quickly.

Hi,

That still only supports one automount location. Currently, a map has to be 
redefined in every
automount location if the same map is to be used for several locations.

My request is to be able to share maps between the automount locations, as well 
as having the per

They are out of scope of the winsync agreement.

Let's say you have in AD
cn=Users,dc=example,dc=com
cn=Adminusers,dc=example,dc=com

and in IPA
cn=users,cn=accounts,dc=example,dc=com

and you set up your winsync agreement as

nsds7WindowsReplicaSubtree: cn=Users,dc=example,dc=com
nsds7DirectoryReplicaSubtree: cn=users,cn=accounts,dc=example,dc=com

That is, you want users in cn=Users,dc=example,dc=com to be in sync with 
cn=users,cn=accounts,dc=example,dc=com


IPA uses a flat dit - users are grouped not by hierarchy but by 
attributes, as opposed to AD which uses hierarchies for grouping.  So 
IPA flattens hierarchies when it syncs users from AD to DS.


Let's say you have
cn=jsmith,cn=Adminusers,dc=example,dc=com with samaccountname: jsmith
and
uid=jsmith,cn=Users,dc=example,dc=com

because of the way that winsync works, it will think because the AD 
entry and the IPA have the same userid, they should be in sync - but 
because cn=jsmith,cn=Adminusers,dc=example,dc=com is outside the scope 
of cn=Users,dc=example,dc=com winsync will think that the user has moved 
outside the scope of the agreement, and will delete the user.  Obviously 
it should not do that by default, hence 
https://fedorahosted.org/389/ticket/355


But why do you have users with the same userid in AD out of the scope of 
the sync agreement with the same userid as an IPA user?


and how do I put legit users in scope?

?


and why doesnt the winsync doc section at least comment (obviously) that I have

change scopes?

kind of bad news when I lose all my users...

Hi,

So I have 6.3 and just lost all my IPA users. So anyone on 6.2/6.3 until they 
upgrade after December's 6.4 could lose all their IPA users if they do a 
winsync agreement and dont twig to that option being essential if they dont 
have a std AD.   Not only that my admins are in a separate OU, so even if I had 
done a --win-subtree=cn=staff_users admins being elsewhere would have gone bye

Luckily I hadnt disabled the admin account yet.it was the only one left.

it should not do that by default, hence 
https://fedorahosted.org/389/ticket/355


But why do you have users with the same userid in AD out of the scope of 
the sync agreement with the same userid as an IPA user?






Luckily I hadnt disabled the admin account yet.it was the only one left.

I guess this stuff is a lot more complex than it looks.

Re: [Freeipa-users] clients very slow

 Hello Everyone,

  

 I work at a small university and I deployed freeIPA on my Linux
 network over the summer break with no (known) problems,  and
 everything worked as expected.  However, now that the semester has
 started and the Linux system is under a much higher load, I am
 noticing that my client machines will randomly slow to a crawl.  For
 example, I have a lab of 25 machines.  The students can log in ok, but
 after a time, a few of the machines will freeze so that the users on
 those machines cannot do anything.  After a few minutes, the frozen
 machines will unfreeze, but other machines will freeze up.  I can't
 see any pattern to what machines freeze up.  I did not have this
 problem when running NIS, so I suspect it is something in freeIPA but
 I am not sure what to look for to solve the problem.  Probably a
 setting somewhere needs tweaked but I don't know.  The server and
 clients all run Scientific Linux 6.2.

  

 Can anyone help me troubleshoot this?


Do you use SSSD as a client or something else?

If SSSD we would need the nsswitch, pam, krb5.conf, sssd.conf
configuration files and SSSD logs set to debug_level=8 or 9.

What operation they are freezing on? Is it login/authentication or just
suddenly, which probably indicates identity lookup.
So freezes might be related to the DNS or name resolution lookups that
those machines do. They might be accessing a DNS server that is down or
misconfigured before failing over to a correct one.

So resolve.conf, /etc/hosts would be helpful.
But you might need to check the DNS configuration yourself.

 Thanks!
