The syncrepl consumer acts as a client with respect to the producer DSA; as a consequence, to be able to perform simple bind, it needs to provide the credentials in cleartext. Either you use a bindmethod different from simple (e.g. SASL) which does not require cleartext credentials (e.g. GSSAPI) or you'll ever need to provide cleartext credentials.

I've committed a preliminary slapd-config.5 manpage to HEAD. In anticipation of deleting slurpd from RE24, I have commented out all of the slurpd-related keywords. Most of the text is the same as in slapd.conf(5) but I've changed the organization to better reflect the actual implementation. There may be options that I've missed. Please review and send patches / corrections / comments. -- -- 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/

If I'd trust the network I'd have | no need for TLS at all... Clearly the user should have an /etc/ldap/ldap.conf under any normal circumstance, and a configuration that does not is most likely broken. However, my argument is that while there may be cases where a user creating a security vulnerability through a broken configuration is simply the user's problem, I believe this is a case where the action taken has no intuitive connection to security. This was initially noticed because a user was putting all their LDAP options in /etc/libnss-ldap.conf rather than in /etc/ldap/ldap.conf, which may be broken but which is not something that is obviously broken from a *security* standpoint. Having a library attempt to open files in the current directory and read them for configuration is highly non-intuitive and unexpected. Having it read configuration out of the user's home directory is less so, but in the case of setuid programs is still rather disturbing, particularly since the setuid program has no direct control over this behavior. So, I see two potential problems here: * A user can override the LDAP configuration of a setuid binary and cause it to, for instance, trust LDAP servers that it wouldn't otherwise trust, which is a potential attack (albeit a difficult one to exploit). If the setuid binary knows that it's using LDAP, it can avoid this via an environment variable, but frequently given such things as NSS plugins and PAM modules the binary isn't going to know that LDAP is involved. The primary problem here is that said setuid binary will read the configuration file based on HOME from the enviroment (it appears to me from the code) or the current directory (the above example), which violates one of the standard secure programming practices for setuid binaries (never trust the process environment including working directory that you're handed by the user). * The library may fall back to reading a file out of the current directory. I don't know if this behavior persists in 2.3; the above example is from 2.1. If it does persist, it opens other potential problems that don't involve setuid but instead involve creating files in the current working directory of a process one wishes to attack. Again, due to the plugin nature of current operating systems, the process being attacked may not even be aware that it's using LDAP. I think this exploit is unlikely to occur in practice since it requires some attacker control over the home directory of the process being attacked, but it's theoretically present. Steve's patch addresses the first issue but doesn't do much about the second, so it's an improvement but I'm not sure it's a complete solution. Unfortunately, this support is also important for the current functionality of the command-line tools and doubtless other programs that use the LDAP libraries. What we ideally need is some way for a user of the LDAP libraries to say, through the API, that user configuration files should not be loaded but that isn't a process-wide flag that interferes with the expected behavior of other uses of LDAP elsewhere in the same process. And as mentioned, I don't see an obvious way to do that without changing the API, which is, of course, a pain. In the meantime, the patch isn't exactly something I'd want to take upstream either, but it at least addresses the most obvious problem, and more problematically I don't see a better way of addressing it other than saying "well, anyone without a system-wide ldap.conf loses." And I wouldn't be comfortable trying to defend that position. I suppose another possible workaround specific to the NSS module (and probably the PAM module as well) would be to proactively check whether there's a system-wide ldap.conf file and fail immediately if there isn't. That leaves the problem open for other setuid uses of the LDAP libraries, but I don't expect there are a lot of those and what ones there may be are more likely to be able to use the LDAPNOINIT flag. -- Russ Allbery (rra(a)debian.org) <http://www.eyrie.org/~eagle/>

(ITS#4751) back-perl crashing with anonymous search request

Full_Name: Ralf Haferkamp Version: HEAD, RE23 OS: SUSE Linux 10.1 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (89.166.155.116) I created a simple back-perl setup with the SampleLDAP.pm Module (slightly enhanced with a bind() method that just returns SUCCESS) from CVS Head and slapd crashed on me immediately on receiving the first anonymous search request. It survived however when I issued bind requests followed by search request. While digging through the code I found that back_perl_bind calls "PERL_SET_CONTEXT( PERL_INTERPRETER );" since a few revisions. All other back_perl_* functions (search, delete, modify, ...) do not call PERL_SET_CONTEXT, adding that seems to fix the crash. The perlembed man-pages state related to PERL_SET_CONTEXT: "PERL_SET_CONTEXT(interp) should also be called whenever "interp" is used by a thread that did not create it (using either perl_alloc(), ..." I'll commit a fix that adds PERL_SET_CONTEXT calls to the other functions as well (wrapped behind #ifdefs just like in back_perl_bind()).

Re: (ITS#4750) libldap initialization of ~/.ldaprc and setuid
by Kurt＠OpenLDAP.org 14 Nov '06

It was my intent when ldap.conf(5) was designed that it only provide defaults when selected by the user. For instance, a hostname when the user provides none. While libldap always read ldap.conf/.ldaprc, that wasn't considered a big deal. However, with various init options which are used without program selection, programs need now to provide an option to disable initialization. Ugh. I have noted that if I had to do it all over again, libldap would never read ldap.conf(5). Instead the program would have to separately call out to facility to obtain defaults. Some of RRA suggests are not workable. For instance, as now some options can only be set via ldap.conf(5)/.ldaprc, disabling it for root disallows root to use all features of programs and the library. But this is all water under the bridge. The library is what it is. Changing it would likely break other things. I note that nss/pam-ldap setting NOINIT (or otherwise mucking with libldap options) might break LDAP-enabled programs. But that's another matter. Anyways, I think the only good fix (for this and many other larger problems) is a library redesign/rewrite.

Re: (ITS#4747) Function nisNetgroupTripleValidate fails on underscores
by temp1＠ips.gov.au 14 Nov '06

14 Nov '06

G'Day Kurt Yes, RFC 2307 is restrictive re: limiting the legal character set for the nisNetgroupTripleSyntax values to a "keystring" (ref: RFC 2252). What I find irksome probably boils down to:- Since LDAP was originally designed to gateway requests to X.500 servers that the character set of an IA5String should be legal. (RFC 2307, section 2.4, X.500 nisNetgroupTripleSyntax) With the added twist of the knife, that underscores are legal in the user CN's when doing the nisMapName=netgroup.byuser Note: OS specific "bad chars" still need to be taken into account by the implementer. Since the "nisNetgroupTripleSyntax" is unlikely to change from "keystring" to IA5String in the near future for OpenLDAP, I think I'll have to consider our options re: netgroup configuration and use.

TIMEOUT is right now unused in the code; have no idea what it was originally intended for. Support for NETWORK_TIMEOUT in ldap.conf is already implemented in HEAD; OpenLDAP 2.3 is feature frozen, so it's unlikely that it will be backported, as it's not a major bug but rather a missing feature. p.

These options are very useful to the wide list of applications, which do not operate these parameters directly: samba, isc dhcp/bind, sendmail and many other things. I offer two variants: with use ldap_set_option: ftp://ftp.openldap.org/incoming/alex-deiter-061112.patch and without it: ftp://ftp.openldap.org/incoming/alex-deiter-061113.patch Thanks a lot!
