Hi There I am trying to setup our kerberos to work with incremental propagation. Currently its turned off and we push updates from master to slaves. I am able to get iprop to work but it looks like we need to change the kpropd slave setup. We at present run it out of inetd but it looks like we need to take it out of inetd and run kpropd on the slaves in a standalone daemon mode. If this sounds not right, please let me know.
>From the MIT documentation for iprop i see "The normal kprop mechanism is >disabled by the incremental propagationsupport. However, if the slave has >been unable to fetch changes fromthe master KDC for too long (network >problems, perhaps), the log onthe master may wrap around and overwrite some of >the updates that theslave has not yet retrieved.

So as stated above in case of issues, will the slave be requesting a full propagation and pulling the full copy or does it have to be initiated by the master via kprop. If the master has to initiate a kprop, the kpropd on the slave is not going to be listening on the same port, i think this would be a problem. 2) How can we manage the size of iproplog specified using iprop_logfile, what is the best way to rotate it? 3) Is the update log same as the one specified with iprop_logfile, it seems that way from the documentation. Any other info on best practices for switching to iprop pull configuration would be appreciated.
