Hi

I am migrating to freeipa from openldap and have around 4000 clients

I had openned a another thread on that, but chose to start a new one here
as its a separate issue

I was able to change the nssslapd-maxdescriptors adding an ldif file

cat nsslapd-modify.ldif
dn: cn=config
changetype: modify
replace: nsslapd-maxdescriptors
nsslapd-maxdescriptors: 17000

and running the ldapmodify command

I have now started moving clients running an openldap to Freeipa and have
today moved close to 2000 clients

However, I have noticed that IPA hangs intermittently.

running a kinit admin returns the below error
kinit: Generic error (see e-text) while getting initial credentials

from the /var/log/messages, I see this entry

 prod-ipa-master-int kernel: [104090.315801] TCP: request_sock_TCP:

Aug 18 13:04:37 prod-ipa-master-int sssd_be: GSSAPI Error: Unspecified GSS
failure.  Minor code may provide more information (KDC returned error
string: PROCESS_TGS)

Could it be possible that its due to the initial load of adding the clients
or is there something else that I need to take care of.

Thanks,

Rakesh
