[Issue 9957] New: slapo-dynlist manpage needs better description of dynlist-attrset

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9957 Issue ID: 9957 Summary: slapo-dynlist manpage needs better description of dynlist-attrset Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Each dynlist-attrset defines one of three distinct behaviours: - dynamic list (attributes are gathered from other entries) - dynamic group (DNs are gathered based on other entries) - static group (DNs are gathered based on DNs stored on entries) With the groups possibly being recursive, requiring traversal. Since the above do not mix, the documentation should be more explicit about how each one should look and behave. It should also be noted somewhere what happens (or not) when multiple dynlist-attrset stanzas would apply to the same entry. At that point, configuration code could also be made more strict to reject configurations that satisfy the apparent dynlist-attrset syntax but do not actually represent anything that fits just one of the above and is therefore nonsensical (with parts of it apparently ignored at runtime). With nonsensical configuration rejected, it would be possible to streamline internal dynlist structures and make critical parts of the overlay code more readable. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9931] New: test079 broken on MacOSX

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9931 Issue ID: 9931 Summary: test079 broken on MacOSX Product: OpenLDAP Version: 2.5.12 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: build Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- Strictly-conforming getopt doesn't allow mixing of -options and plain args. All documentation shows that LDAP attributes must be last on the ldapsearch commandline, but the script is putting additional -options after the olmDbConnURI attribute specification, which causes the following -options to be ignored and the search command fails. -- You are receiving this mail because: You are on the CC list for the issue.
