Re: [Freeipa-users] Difficulty installing freeipa



Hi,

Where is DNS being done and how?

I tend to agree with Dmitri, it looks like DNS related issues.

regards

I’m not using a VM, I’m using a workstation dedicated to just FreeIPA.  It has 4GB memory.
Which logs are you interested in?  I’ve been looking through all I can find and have seen nothing relevant.

 I continue to work with performance issues.  I went into the krb5.conf and changed dns_lookup_kdc from true to false.  Kinit now responds immediately.  It’s cut the time on “ipa-finduser admin” from 2m30s down to 18-20s.  How fast “should” this respond?


 It should be a matter of less than a second.
 Are you using a VM to test? Does it have enough memory?
 It is really hard to say what exactly is causing your delays.
 IPA does a lot of name resolution. Delays usually related to that. By turning off the name resolution against DNS in Kerberos you reduced number of the lookups but probably not eliminated all of them. I suggest you continue looking into the name resolution more.
 This is the best we can say without any logs or specific configurations. Sorry.

 Thanks
 Dmitri
