1 ODMaster + 4 Replicas
over 1000 clients in Directory

setup has been working fine for over a year now serving up user info for 10.2.x-10.4.x clients.

all of the sudden a few clients stopped being able to log in.

Nothing about not finding the AFP share or homedirectory or anything.. login window just shakes.. (usually an authentication problem eh?)

logged in via local user and can connect to AFP share of network user OK.
Can ssh to server and even get a Krb ticket via kinit from terminal for Network user.


90% of the clients can login just fine. Most of the ones having the problem seem to be 10.3.9 machines.

on the server that these clients would be authenticating against (happens to be the OD master)
only thing I happen to see in the logfiles that might indicate a relevant problem...


a bunch of (in PasswordService logs)
LaunchTaskWithIO path =/usr/sbin/kdb5_util, arg1 = dump, arg2 = -, status = 1


also it seems that replicas seem to be constantly wanting to update the records..
a bunch of Sync processes keep repeating over and over..


nothing really in the krb or opendirectory logs...

System works fine for most users still...

quadruple checked config in Directory Access on affected machines, and have starting banging head on the wall..

On the client machines, only log that really seems to give up any info related to login attempts are in secure.log, but only message seems act like it's a bad password.

any ideas? something else I could check? more info I could provide for assistance?


thanks for any help.

Hello Chris,

Some things you may want to try for 10.3.9 are:

On the client change /System/Library/StartupItems/LoginWindow/ StartupParameters.plist

From this:
{
  Description     = "login window";
  Provides        = ("Multiuser Login Prompt");
  Requires        = ("Disks", "SecurityServer");
  Uses            = ("Core Graphics");
  OrderPreference = "Early";
}

To this:
{
  Description     = "login window";
  Provides        = ("Multiuser Login Prompt");
  Requires        = ("Disks", "SecurityServer", "Network");
  Uses            = ("Core Graphics");
  OrderPreference = "Early";
}

This resolves an issue where the login window starts up before the system has a stable network connection.

On the client make sure that /private/Network/Servers is filled with aliases not actual files. If there are files in this directory you can rename/delete the Servers directory and reboot. A corrupt cache file can also cause an issue. Try renaming /Library/Caches and rebooting.

Check to see if there is anything in the system and secure logs on the client. You could also bump up the log level in /etc/syslog.conf on your clients and server.

Hope this helps!
