LDAP is the only builtin KDC backend that supports multi-master KDCs at all. (I don't know whether there are any public out-of-tree backends that do so.) So, while you could use the LDAP backend with a single LDAP master and multiple KDC masters, that master LDAP server would be a SPOF. -Ben

Hi Thor. So you have a shared ldap? If so, could that ldap be a single point of failure? Thanks, Yegui On Sat, Feb 2, 2019 at 11:10 AM t Seeger wrote: > Hey Yegui, > > I use a mutli master setup. For the sync I use openldap. > > Greeting Thor > > On 2. Feb 2019, at 15:38, Yegui Cai wrote: > >
