Hi, During our many tests, we've seen a particular behaviour in certs checking, so wewander if it is not as misconfiguration of our server : We have installed 2 FDS and replication agrements between it. Those replication agrement are configurated with the "SSL connection" option enable, "simple authentification" and a replication manager. A certificate have been generated for each server, using is FQDN. Replication is ok. However, we 've made a mistake in a tests, and one cert was generated with DNS hostname different from the server it was destinated for and replication is still working... How is it possible ? Is there any hostname controle in the SSL connection ? Ex: toutou.gaia.net (with cert signed toutou.gaia.intranet.net) is replicating with gri.gaia.net (with cert signed gri.gaia.net) BR, -- ========================================== Emmanuel BILLOT IRD - Orl?ans D?l?gation aux Syst?mes d'Information (DSI) t?l : 02 38 49 95 88 ==========================================
