This purpose is, I think, somewhat beyond the intended purpose of the vendorName/Version attributes. These attributes appear to be intended to be used by general LDAP clients, not just administrative clients, for "limited feature discovery". The vendorName/Version you might want reported for "limited feature discovery" might be quite different than what you want reported for "need to upgrade" purposes. And for "need to upgrade" purposes, one needs to know not only the version of the protocol engine (slapd(8)), but version of backend codes, overlay codes, underlying libraries, etc.. >> We provide cn=monitor for this purpose. > >This is proprietary.

The server admin can easily define access control for vendor information in root DSE. The sample slapd.conf could endorse this. Or another value for configuration directive 'allow'. Ciao, Michael.

The only reasonably decent use of such attributes is for administrators to determine whether they need to upgrade some software or not (though use of a protocol attribute for this purpose is somewhat problematic). We provide cn=monitor for this purpose. The primary use (or I should say misuse) of such strings is for server behavior discovery (whether the behavior is due to a feature or a bug). As this use leads to interoperability problems (as illustrated by the HTTP "mozilla" compatibility problems), we must allow spoofing and should discourage this use. We support the former via the rootdse configuration option. We support the latter by not providing any values by default. While it certainly is possible for a client to abuse cn=monitor version information, the very fact that the version information is in cn=monitor, which generally requires special authorization to read, instead of the root dse, which generally is readable by most every client, is effective in discouraging this abuse. I think it reasonable to assume any administrative tool for determining whether an OpenLDAP server is up to date would have appropriate authorization to read the cn=monitor values. I note that such tools should not assume a server needs not be upgraded simply because the version is high enough. There easily could be dependent software whose version is not high enough. It would be good for cn=monitor to not only expose the OpenLDAP version information, but to expose version information for dependent software. Of course, as there is an endless number of dependent software, this upgrade detection approach problematic. Seems it would be better to use tools that ran directly on the box to determine whether a server's software needed to be upgraded. But I digresss. In the past we have rejected submissions to extend slapd(8) to generate these values, hence I think this feature request should be closed. However, such closure certainly doesn't preclude someone from implementing **additional** vendorName/Version functionality and submitting it for consideration. There is one aspect of our current vendorName/Version support that is lacking is in dealing with multiple broken clients requiring different vendorName/Version strings. An overlay which spoofed these strings on a configurable basis, whether by authorization identity and/or IP address and/or other authorization factor, would be an interesting functionality addition.

RE: (ITS#4756) IPv6 Addresses are not supported in ACL peername
by Damon.Groenveld＠ca.com 16 Nov '06

16 Nov '06

Given that the code (in aclparse.c) calls inet_addr() with the peername.ip parameter, I can't see how it could will work with IPv6. The only possible workaround is using a regex instead of ip type which by passes the inet_addr() call. I raised it as a bug since the latest version (as far as I can tell) is meant to support IPv6 and there is no way that peername.ip does and there isn't an alternative. I asked the question regarding other ways to restrict access since I noted that the documentation mentions TCP Wrappers and has a see also of host_options(5) -- which does not exist, so I was hoping that some advice might come while someone looked at the problem (if or when it was deemed important enough).
