For GSSAPI it should probably just say not to specify olcSaslRealm at all since the mechanism has its own notion of realms already. Most likely you would only set this for something like DIGEST-MD5 which uses realms but doesn't inherently know its own realm name. > --- sasl.sdf.orig 2011-01-03 09:45:55.754879001 +0000 > +++ sasl.sdf 2011-01-03 10:07:34.808208000 +0000 > @@ -135,25 +135,35 @@ > For the purposes of authentication and authorization, {{slapd}}(8) > associates an authentication request DN of the form: > > -> uid=<primary[/instance]>,cn=<realm>,cn=gssapi,cn=auth > +> uid=<primary[/instance][@realm]>,cn=gssapi,cn=auth > + > +The realm is omitted by Cyrus SASL if it's equal to the default realm of the > +server in {{FILE:/etc/krb5.conf}}. > > Continuing our example, a user with the Kerberos principal > {{EX:kurt@EXAMPLE.COM}} would have the associated DN: > > -> uid=kurt,cn=example.com,cn=gssapi,cn=auth > +> uid=kurt,cn=gssapi,cn=auth > > and the principal {{EX:ursula/admin@FOREIGN.REALM}} would have the > associated DN: > > -> uid=ursula/admin,cn=foreign.realm,cn=gssapi,cn=auth > +> uid=ursula/admin(a)foreign.realm,cn=gssapi,cn=auth > > > -The authentication request DN can be used directly ACLs and > +The authentication request DN can be used directly in ACLs and > {{EX:groupOfNames}} "member" attributes, since it is of legitimate > LDAP DN format.

Except maybe people will start to quote the URLs more. -- Hallvard

I would need to > detect the memberof-overlay and find the correct string or pointer to > compare to. I will gladly do so if you can give me some hints where to look. AttributeDescriptions are a fundamental data structure used throughout the code. It would be impossible to have read any of the existing overlay code without encountering countless examples of their use. There is no need to detect the memberof overlay. All you need to do is provide a configuration option to specify the attribute you are going to treat as a memberof attribute. >> You're using strcasecmp, but your inputs are already normalized >> values.

Short answer - use an NSS client that actually supports RFC2307bis, like every other vendor in the world already does. In the meantime, if you submit a cleaned up patch that makes better use of the slapd APIs, we can review it again. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

In short, no. The underlying archives are the email messages submitted to the list stored in mbox format, which are then reformatted to HTML using off-the-shelf software. While it technically possible to hack that software to do all kinds of reformatting (as we have the source), we don't have the resources to maintain a custom fork of that software. However, there may be an reasonable alternative suggestion. The ITS software itself could be modified to include a URI to the issue in each message it sends. This would not only show up in archives, but in mail distributed to -bugs list and directly to users of the system.
