[Freeipa-users] Server error with multiple clients joining domain simultaneously

[David Zabner]

I was guessing that it was a problem with mod_auth_gssapi and so I tried switching the auth method back to mod_auth_kerb which did not work. (although it is entirely possible that I did not switch it correctly)

I did it by changing the gssapi settings in /etc/httpd/conf.d/ipa.conf to:
<Location "/ipa">
  AuthType Kerberos
  AuthName "Kerberos Login"
  KrbMethodNegotiate on
  KrbMethodK5Passwd off
  KrbServiceName HTTP
  KrbAuthRealms $realm
  Krb5KeyTab /etc/httpd/conf/ipa.keytab
  KrbSaveCredentials on
  KrbConstrainedDelegation on
  Require valid-user
  ErrorDocument 401 /ipa/errors/unauthorized.html
</Location>
It just seemed to cause other problems...

I should add that some of my team members have tried serializing their instance launches, and this problem does not seem to occur under those circumstances.  (That’s not a solution, just a data point for those interested in this behavior).  Thanks.

This sounds exactly like the problem I am having. I will attach my error log. Is this what yours looks like?
