Re: FreeIPA missing replication segments but still replicating
by Florence Blanc-Renaud
Hi,
do you have a kerberos ticket for the "admin" user when the "ipa
topologysuffix-show" command (or any other ipa command) is called? Some
commands require admin privileges to access the data, and will not display
anything if they are executed without an admin ticket.
Please try with "kinit admin; ipa topologysuffix-show" and let us know if
it solves the problem.
