Re: got into a "checksum error" situation

by Jeff Dickens

Yes, I edited it by hand. Clearly not advisable since the comments said "don't do that", but since the server wouldn't start I couldn't use ldapmodify.

access to inherited attributes

by Michael Ströder

HI! I cannot find anything in slapd.access(5) indicating that access attrs=mysupattr by <who> <access> also grants <access> to attributes inherited from mysupattr (which have SUP mysupattr in the attribute type description). Is this the expected behaviour? Where is this documented? (testing with 2.4.32) Ciao, Michael.

access granted So far so good, all four modification operations succeeded. That's slapd's known default behavior and completely correct in regard to the above defined acl. My intention is to let the first three operations (to value(s)) succeed and the last operation (to all values) fail by "Insufficient access (50)". After studying the documentation, doing some (unstructured, trial and error) testing with various combinations of acl statements, I finally had a closer look into slapd's source: Am I right, that slapd's acl engine currently does not offer a chance to differentiate between these two types of modification?

critical applications

by Friedrich Locke

Dear friends, i am planning to use openldap 2.4.26 and bdb 4.6.21v0 for mission critical application mailing system. I tried some time ago i tried to implement a mail server using qmail, qmail-ldap patch, openldap and bdb but while time passed and email were coming and going, slapd was eating all system memory and needed to be restart. I wonder if someone in the mailing list have used such technologies so far and with which degree of success ? Thanks in advance for your time and cooperation. Best regards. []s gustavo.

ACL: access to all values vs. to value

by Dora Paula

Hi list, is there a possibility to create an acl statement that grants access to any (unknown) value of an attribute but denys access to all values of the same attribute? For example: # allow this: dn: cn=PersonA,ou=persons,o=test changetype: modify delete: description description: PersonA's description # deny this: dn: cn=PersonA,ou=persons,o=test changetype: modify delete: description - Thank you very much.
