Problems creating an OD replica

[Commander Keen]

Hello,

I’m currently running into some LDAP-related troubles, I was hoping maybe you could help me out…

I’m getting this strange error while trying to create a replica for my LDAP-server.
When looking in de slapconfig-log on the “wannebee”-replica, It seems like there’s an error occuring while trying to replicate the OD Password server (in advance, starting up the replica itself, and Kerberos seems to go fine).

Looking at the master, I’ve found an ApplePasswordServer.Error.log file (in /Library/Logs/Passwordservice), only containing the following line:
Date/time Listener exception error:-1.

That doesn’t quite clear things up, does it 🙂
Can’t figure out what exactly seems to be the problem.

Do you guys have any idea what might do the trick?
It happens on several machines, clean install, DNS correctly working…all on 10.4.3

Thank’s in advance

we had the same issue a few days ago while trying to repair an odd kerberos issue.

we noticed that the file : /var/db/authserver/authserverreplicas had a size to 0 on the master.

——————————————————————————–
assuming

FQDN : foo.bar.com
IP : 192.168.1.250
REALM : FOO.BAR.COM

——————————————————————————–
the solution applied was to remove ervery kind of kerberos information on the master with :

sudo rm -f /var/db/krb5kdc/*
sudo rm -f /var/db/krb5kdc/.k5.FOO.BAR.COM
sudo rm -f /Library/Preferences/edu.mit.Kerberos
sudo rm -f /etc/krb5.keytab

sudo scutil –set HostName foo.bar.com

dscl localhost

> cd /LDAPv3/127.0.0.1/Config/
/LDAPv3/127.0.0.1/Config > auth
Password:

/LDAPv3/127.0.0.1/Config> delete KerberosClient
/LDAPv3/127.0.0.1/Config> delete KerberosKDC

sudo reboot

Then, kerberize the server again with :

kerberosautoconfig -r FOO.BAR.COM -m foo.bar.com

kdcsetup -f /LDAPv3/127.0.0.1 -w -a admin -p ***** FOO.BAR.COM

sso_util configure -r FOO.BAR.COM -a admin -p ***** all
sso_util configure -r FOO.BAR.COM -a admin -p ***** ldap

mkpassdb -kerberize

Verify your job :

make a new replica with SA, it should work.

[nigelkersten]

I’m running into this same problem at the moment, and the fix above doesn’t work.

I’m not sure why it would anyway, destroying and creating the Kerb config won’t touch the authserver config.

I don’t have authserverreplicas at all as a file, and I can’t seem to construct it by hand either…

[nigelkersten]

ok, after chatting to mactroll, he’s given me a solution.

If you don’t have any existing replicas, this will work fine. I imagine that if you do have existing replicas, you’d probably want to tear them down first.

trash the authserverreplica* files in /var/db/authserver (well really, you should probably back them up first)
kill -9 the PasswordService process.

It will start up again, and create the authserverreplica file, just listing the primary PWS itself as a replica.

Then I was able to create replicas happily enough.

During the summer our school district installed 4 10.4.servers, one as an OD master and 3 as replicas, the servers were divided between two schools. The school where the replicas resided started having issues with user logons and computers freezing. This past week the school got so bad in WGM that we had to reinstall 10.4.3 on 2 servers. We divided up the schools so that each has it’s own OD master, it is a hassle to manage 2 databases. Then we upgraded one server to an master but the other server will not become a replica. The replication process seems to go thru then the server reverts back to a standalone, the logs state the replica is denied and there is password service error. This is on new clean installs. We tried the fix on the kill password service and deleting the authreplicas file but that did not work.
We are still working on fixing this mess.

If anyone has any other suggestions it would be appreciated. It would be nice if the OS worked like it should.

Running into the same problem …

I’ve deleted the replicas (have only one replication server) and tried again.
Now I’m getting a different error number (78) for the NeST command. The password server error log claims to not to be able to reach the client.
This is surprising, as I can ping, ssh, scp, run Server Admin, etc and netstat on the server shows that the route is properly setup. Can it be, that the replicator software has problems when both nics are in use?

I have one (the built in one) set up as connected to the internet (the default gateway is there), the other connected to an intranet, which is served by the server via NAT. The client also has two connections, one to the internet, the other to the same intranet. Hmm, maybe I have to use the internet connections?
