Specifies the policy to use for reconnecting to an unavailable LDAP server. The default is hard_open,which reconnects if opening the connection to the directory server failed. By contrast, hard_initreconnects if initializing the connection failed. Initializing may not actually contact the directory server, and it is possible that a malformed configuration file will trigger reconnection. If soft is specified, then nss_ldap will return immediately on server failure. All “hard” reconnect policies block with exponential backoff before retrying.
