Maybe it was caused by invoking 'make install' as root while still running 'make test' as normal user. Ciao, Michael.

(ITS#5717) slapo-dynlist expantion failed for mapped attributes
by menu＠netbsd.org 29 Sep '08

29 Sep '08

Full_Name: Emmanuel Dreyfus Version: OpenLDAP-2.4.11 OS: NetBSD-4.0 URL: Submission from: (NULL) (193.54.82.42) If slapo-dynlist is configured with attribute mapping, dynlist expantion will only work if the member attribute in included in the searched attriute set. Here is an example: Config: overlay dynlist dynlist-attrset ExMailAddress memberURL mailbox:revalias Searched entry: dn: mailAddress=foo-employee(a)example.net,o=ex objectClass: exMailAddress mailAddress: foo-employee(a)example.net memberURL: ldap:///o=ex,revalias?sub?(&(objectClass=exPerson)(employer=foo)) Expantion looks up objects like this: dn: uid=jdoe,o=ex objectClass: exPerson uid: jdoe revalias: john.doe(a)example.net employer: foo With the member attribute in the searched attribute set: $ ldapsearch mailAddress=foo-employee@example mailbox revalias dn: mailAddress=foo-employee(a)example.net,o=ex mailbox: john.doe(a)example.net mailbox: joe.luser(a)example.net mailbox: emmanuel.dreyfus(a)example.net Without it: $ ldapsearch mailAddress=foo-employee@example mailbox dn: mailAddress=foo-employee(a)example.net,o=ex Note that if no attribute set is provided, it works: $ ldapsearch mailAddress=foo-employee@example dn: mailAddress=foo-employee(a)example.net,o=ex objectClass: exMailAddress mailAddress: foo-employee(a)example.net mailbox: john.doe(a)example.net mailbox: joe.luser(a)example.net mailbox: emmanuel.dreyfus(a)example.net memberURL: ldap:///o=ex,revalias?sub?(&(objectClass=exPerson)(employer=foo)) I should provide a fix for that soon.
