(ITS#6817) idassert-bind with SASL issues
by masarati＠aero.polimi.it 31 Jan '11

31 Jan '11

Full_Name: Pierangelo Masarati Version: HEAD/re24 OS: irrelevant URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (2.40.14.92) Submitted by: ando When idassert-bind is configured to use SASL bind, an "authcID" needs to be provided, while the "binddn" is not needed. However, if a "binddn" is not provided as well, in some cases the proxiedAuthz control may be used incorrectly. The need to configure the "binddn" is not documented, so this ITS is minimally addressed by documenting this requirement. If the "binddn" is provided, everything works as expected, with the only minor issue that the DN of the user as it is known to back-meta may not match the actual identity the "authcID" assumed on the remote server. The "right" way to address this problem consists in performing a "WhoAmI" (RFC 4532) right after the bind, or better use a "authorization identity control" (RFC 3829) along with the bind operation. Both approaches should be implemented, but they should not be used unless explicitly requested. p.

Man page TLS settings and directives, and Admin Guide. I tested the man pages, but I wasn't sure how to generate the docs from the .sdf files - hopefully they will work ok without extensive changes.

Hmm, I'm not quite seeing what you're saying here. For example, in slapd.1.log, *before* ppolicy_forward_updates (olcPPolicyForwardUpdates) is enabled, I can see the certificate being mapped exactly as I expect it: ===== ==> rewrite_context_apply [depth=1] res={0,'cn=localhost,dc=example,dc=com'} [rw] authid: "cn=localhost,o=openldap,st=some-state,c=us" -> "cn=localhost,dc=example,dc=com" [...] <==slap_sasl2dn: Converted SASL name to cn=localhost,dc=example,dc=com slap_sasl_getdn: dn:id converted to cn=localhost,dc=example,dc=com SASL Canonicalize [conn=1004]: slapAuthcDN="cn=localhost,dc=example,dc=com" SASL proxy authorize [conn=1004]: authcid="cn=localhost,o=openldap,st=some-state,c=us" authzid="cn=localhost,o=openldap,st=some-state,c=us" conn=1004 op=1 BIND authcid="cn=localhost,o=openldap,st=some-state,c=us" authzid="cn=localhost,o=openldap,st=some-state,c=us" SASL Authorize [conn=1004]: proxy authorization allowed authzDN="" send_ldap_sasl: err=0 len=-1 conn=1004 op=1 BIND dn="cn=localhost,dc=example,dc=com" mech=EXTERNAL sasl_ssf=0 ssf=256 do_bind: SASL/EXTERNAL bind: dn="cn=localhost,dc=example,dc=com" sasl_ssf=0 ===== Based on this, I'm assuming that my authz-regexp is behaving as I'm intending -- looking for a certificate with "cn=localhost" anywhere in the subject DN, and mapping that to the DN cn=localhost,dc=example,dc=com in the directory. It's only *after* olcPPolicyForwardUpdates is enabled that the SASL EXTERNAL authentication stops working. Can you help me understand the disconnect between what I'm seeing and what you're saying? > I didn't get this far because your test certificate is now expired.

(ITS#6815) Feature Request: Accesslog filter
by marco.pizzoli＠gmail.com 30 Jan '11

30 Jan '11

Full_Name: Marco Pizzoli Version: ALL OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.41.84.11) Hi, this is a feature request. I would like to have accesslog writing to his db only ldap operations that match some sort of filter, or, in particular, to not to log searches that matches a specific pattern. This request is spotted by some ldap clients that I have that every 30seconds do a dummy ldap search only to keep alive their connection to the ldap server. These searches are frequent and I have many of these clients in my deploy, so my accesslog become full of not significant entries. Thanks in advance Marco Pizzoli

Re: (ITS#6749) Shut up "configure monitor database to enable"

If the admin put 'olcMonitoring: TRUE' in slapd.d but did not include database monitor, that would be poor user config. I'm fine with having bdb set the internal default flag value to TRUE. My protest in that context is against slapd - be it back-bdb or back-config which is to blame - writing the default value to the cn=config LDIF even though the admin never mentioned monitoring. This means that neither the TRUE value of the internal flag nor the presence of the attribute is an indication that the admin asked for monitoring (i.e. set the flag) but forgot to add database monitor. > Maybe this warning can be demoted to LDAP_DEBUG_CONFIG instead of > LDAP_DEBUG_ANY. Yes. Maybe slapd should nag the admin more about bad config, but if so there are plenty of other things which are more important than this and should get a chance to nag the admin before this particular flag gets to do it. IIRC the only other thing which gets to do that now is BDB without DB_CONFIG - which makes sense since that's an entire non-OpenLDAP subsystem which has not been configured. But also: > I understand that one could presume that the lack of database monitor > in the configuration indicates that monitoring is not desired; this > warning, however, tries to address a typical configuration error, when > admins just forget to configure it. No, this is a broken slapd default. It should not be an admin error to not mention a feature he does not want and does not need to know about. And if slapd does nag anyone about it, it should nag admins who do mention either database monitor or the flag, not admins who do not. So slapd should be quiet if it set the flag internally and the admin does not include database monitor. Thus my suggestion to set the flag internally by default but only nag the admin if it was set in cn=config. Unless olcMonitoring:TRUE is a drain on performance or something so it really ought to be off when the data is not used anyway. An alternative (and a change in behavior from now) if you really want this warning, would be to always default monitoring to off. That'll surprise existing users, so the cn=monitor objects could contain some text 'monitoring off for this database, set olcMonitoring to enable'. Personally I don't think a warning is worth such a change in behavior, but then I don't like the warning anyway:-) -- Hallvard
