Hi Bruno, What type of filesystem is BDB located on? I.e., NFS, ext3, SAN, etc. Also, what version of BDB are you using from Oracle? Can you provide your configuration file/cn=config directory (minus any passwords)?

(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.

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.
