After looking a bit more on this I'm more convinced that the alternative fix is the correct. A patch that implements this is attached, all tests succeed with it.

I am fairly sure I saw one place where > the docs specifically exclude some of those forms. Yes, I believe in some cases some of the variants of the syntax are not allowed. This is true, for example, in SASL identity mapping, which does not allow the regex, subtree, children, onelevel, group and users styles, only the base and uri forms are allowed (provided the latter only returns a single match). > I notice that '*' excludes anonymous in this spec.

It is documented (in 2.4, at least; it does not exist for 2.3). > would allowing this cause anon to be included in '*' generally or is > it not that simple? '*' implies a non-empty value; to include anonymous, use "dn.regex:.*", or "dn.subtree:". p. Ing.

If that is used *everywhere* for authorisation then there could well be more doc errors to correct. I am fairly sure I saw one place where the docs specifically exclude some of those forms. I notice that '*' excludes anonymous in this spec. There is an undocumented option to 'allow' that seems relevant: proxy_authz_anon - would allowing this cause anon to be included in '*' generally or is it not that simple?

Not sure what you mean there, but I believe the fact that the implementation is in saslauth.c is for mere historical reasons.
