allowed-client
Synopsis |
A set of clients who will be allowed to establish connections to this Global Configuration. |
Description |
Valid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. Specifying a value for this property in a connection handler will override any value set in the global configuration. |

bind-with-dn-requires-password
Synopsis |
Indicates whether the directory server should reject any simple bind request that contains a DN but no password. |
Description |
Although such bind requests are technically allowed by the LDAPv3 specification (and should be treated as anonymous simple authentication), they may introduce security problems in applications that do not verify that the client actually provided a password. |

denied-client
Synopsis |
A set of clients who are not allowed to establish connections to this Global Configuration. |
Description |
Valid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. If both allowed and denied client masks are defined and a client connection matches one or more masks in both lists, then the connection is denied. If only a denied list is specified, then any client not matching a mask in that list is allowed. Specifying a value for this property in a connection handler will override any value set in the global configuration. |
Default value |
If an allow list is specified, then only clients with addresses on the allow list are allowed. Otherwise, all clients are allowed. |

Description |
Servers pertaining to the group ID of the current server are first tried. If none respond, then servers pertaining to the first group ID in the list are tried. If none respond, then servers pertaining to the second group ID in the list are tried, etc. Finally, when no servers from the listed groups respond, then all the remaining servers are considered. |

je-backend-shared-cache-enabled
Synopsis |
Indicates whether all the JE backends should share the same cache. |
Description |
When enabled, all the JE backends share the same cache. JE backends will make better use of memory: the cache will use around at most 75% of the JVM Old Gen size. Note that when this setting is enabled, it overrides all db-cache-percent and db-cache-size settings. Note also that cache misses in one backend could cause cached data for other backends to be evicted.
