Resolved issues

The following issues have been resolved with this release of the Directory Proxy Server.

Ticket ID Description

Updated setup and the replace-certificate tool to improve the way we generate self-signed certificates and certificate signing requests to make them more palatable to clients.

To reduce the frequency with which administrators had to replace self-signed certificates, we previously used a very long lifetime for self-signed certificates generated by setup or the replace-certificate tool. However, some clients (especially web browsers and other HTTP clients) have started more strenuously objecting to certificates to long lifetimes, so we now generate self-signed certificates with a one-year validity period. The inter-server certificate (which is used internally within the server and does not get exposed to normal clients) is still created with a twenty-year lifetime.

Also, the replace-certificate tool's interactive mode has been updated to improve the process that it uses to obtain information to include in the subject DN and subject alternative name extension for self-signed certificates and certificate signing requests. The following changes have been made in accordance with CA/Browser Forum guidelines:

* When selecting the subject DN for the certificate, we listed a number of common attributes that may be used, including CN, OU, O, L, ST, and C. We previously indicated that CN attribute was recommended. We now also indicate that the O and C attributes are recommended as well.

* When obtaining the list of DNS names to include in the subject alternative name extension, we previously suggested all names that we could find associated with interfaces on the local system. In many cases, we now omit non-qualified names and names that are associated with loopback interfaces. We will also warn about any attempts to add unqualified or invalid names to the list.

* When obtaining the list of IP addresses to include in the subject alternative name extension, we previously suggested all addresses associated with all network interfaces on the system. We no longer suggest any IP addresses associated with loopback interfaces, and we no longer suggest any IP addresses associated in IANA-reserved ranges (for example, addresses reserved for private-use networks). The tool will now warn about attempts to add these addresses for inclusion in the subject alternative name extension.


Fixed an issue in which the Directory Server could incorrectly allow requests to be processed with an alternate authorization identity (for example, using the proxied authorization control, or if the requests pass through a Directory Proxy Server) whose account is in a "must change password" state. The server will now only permit the operation if it attempts to set a new password for the target user.


Reduced the JVM memory requirements for many command line tools. This avoids memory pressure when multiple tools, such as a scheduled collect-support-data task, are run concurrently to the server process. For most tools, the initial heap size has been reduced to 128 MB, and for certain tools the maximum heap size has capped at 512 MB. On systems with larger amounts of memory, these tools previously were allotted unnecessarily large heaps. The maximum heap size has not been reduced for any tool that especially benefits from having more memory.
