Hi all,

We have a 3 master setup that is failing to replicate changes from a particular node to the other IPA instances. The replication status says it's all fine, however the record hasn't been changed on the other servers. We've seen this on user password changes, adding hosts and services. The only thing we've found that seems to fix this temporarily is to re-initialize from the master with the changed record. A force-sync doesn't pick up the changed record.

Not sure what logs would be helpful to diagnose what is happening in this setup.

Any help in what else can be checked or what logs would be helpful would be appreciated.

Thanks
