That test is only supposed to prevent mapping when doing an authzRegexp mapping of a single SASL userID to a DN. When looking up authzFrom/authzTo it is supposed to allow multiple results. Interestingly, it looks like slap_sasl_match isn't even used for authzRegexp mapping any more.

This makes perfectly sense, otherwise a SASL identity (or an authorization identity) would be arbitrarily mapped to one of the matching entries. So mapping is intended to succeed if and only if exactly one identity can be resolved. If the behavior you're experiencing is consistent with the above, there is no evidence of a bug in OpenLDAP software. If it's not, please detail. Otherwise, this ITS will be closed. p. Unless Ing.

(ITS#4744) Bug in SASL authzTo validation using an ldap:// rule
by sylvain＠pilotsystems.net 11 Nov '06

11 Nov '06

Full_Name: Sylvain Viollon Version: 2.3 OS: FreeBSD 5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (83.204.228.114) I have an directory with some users in ou=people,dc=pilotsystems,dc=net branch, having a custom class krbUser ; and a user (cn=auth,dc=pilotsystems,dc=net) having the following attribute : authzTo: ldap:///ou=people,dc=pilotsystems,dc=net??sub?(objectClass=krbUser) He can successfully authenticate, but not become an user listed by the search (with PROXYAUTHZ). Running slapd in debug-mode I saw that he can only become the last user returned by the search. In source, I read the file 'servers/slapd/saslauthz.c'. The filter 'sasl_sc_smatch' said if the wanted user is in the search result. In this function, there is a test : if ( sm->match == 1 ) { sm->match = -1; return 0; } I have removed the line : sm->match = -1; Which make the match to fail if there is an entry in the search return after the good one. Like every DN have to be unique, there is no multiple solution, and validation would not be discarded for that. I didn't know if it's a good solution, but it's work. Openldap 2.2 and 2.4 seems to have the same problem.

ITS#3755 strict aliasing rules
by hyc＠symas.com 10 Nov '06

10 Nov '06

Compiling current HEAD with gcc 4.1.1 make AC_CFLAGS="-g -fstrict-aliasing -O3 -Wstrict-aliasing" -j3 CC=gcc turned up a few "will break strict-aliasing rules" warnings: libldap/cyrus.c libldap/getdn.c clients/tools/ldapsearch.c servers/slapd/sasl.c I've silenced all of those. Whether the code was actually unsafe before and is safer now is anybody's guess; I was unable to get any of it to misbehave with various combinations of optimization switches. There are warnings about using the BerElementBuffer "might break strict-aliasing rules" which I've chosen to ignore. Since the memory is only actually referenced through the BerElement pointer, whether or not the contents are defined when accessing the BerElementBuffer is irrelevant. (I.e., we never access it that way, so it's moot.) -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc OpenLDAP Core Team http://www.openldap.org/project/

However, it would be more appropriate to log configuration errors that result in failures at "any", so that whatever logging is set they show up. For this purpose, many of the current occurrences of LDAP_DEBUG_CONFIG should be turned into (LDAP_DEBUG_CONFIG | LDAP_DEBUG_NONE), so that they show up when caught by tools with default logging (e.g. slaptest(8)), or into LDAP_DEBUG_ANY, so that they show up all times. I'd vote for the latter. Cheers, p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

Full_Name: Michael Ströder Version: HEAD OS: SuSE Linux 10.1 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (83.124.25.247) HI! It seems that slapd stops without configuration error message if unknown attribute types are set for parameter unique_attributes (slapo-unique). It would be nice if a descriptive message is displayed (like in other cases). Ciao, Michael.
