(ITS#5919) URI syntaxe (ldap:///dc=my%2cdc=domaine)

Hi,
The "tool_conn_setup" function (in common.c) autorise the Url synthaxe
"ldap:///dc=my%2cdc=domaine" which produce a SRV request to find the best server
to request (not yet according the rfc 2782 - I've made dnssrv.c patch to
implement priorities and I try to implement weight before submit this work). So,
the client tools - ldapsearch, ldapadd, ... permit this syntaxe (via
"ldap_dn2domain" and "ldap_domain2hostlist" functions).
Unfortunately, ldap_initialize() doesn't use these functions (but only
ldap_url_parselist_ext()) and doesn't allow this synthaxe. So, other packages
(like SAMBA) doesn't enjoy this capability : "passdb backend =
ldapsam:ldap:///dc=my%2cdc=domain" according a SRV definition
"_ldap._tcp.my.domain. IN SRV ..."
Is there any reason for that ? Can we envisage to increase this possibility ?

(ITS#5918) slapacl(8c) badly worded

Slapacl is used to check the behavior of the slapd in verifying access
to data according to ACLs, as specified in slapd.access(5). It opens
the slapd.conf(5) configuration file, reads in the access directives,
and then parses the attr list given on the command-line; if none is
given, access to the entry pseudo-attribute is tested.
Besides the bit about "of the slapd", the first sentence is rather awkward.

A single password change on the provider results in unlocking on the consumer

(ITS#5917) slapd crashes with assertion failed and SIGABRT
by guido＠keamera.org

Version: 2.3.43

Submission from: (NULL) (194.246.126.62)
Hello,
I'm using OpenLDAP 2.3.43 with ldap backend as a proxy to Active Directory for
users autentication on linux(gentoo).
OpenLDAP keep on crashing while testing it through the nss_ldap module using
the "id" unix command. It often crashes for an assertion failed(that i can
easily reproduce) but sometimes with a segmentation fault or a glibc error
related to free()(heap corruption?).
I found as a workaround that if I set the maximum threads number to 2 it works
just fine.
I'm using glibc-2.6.1 with NPTL and I have compiled OpenLDAP with gcc-4.1.2 and
3.4.6.
Here is my slapd.conf, ldap.conf(used by the nss_ldap module) and some
backtraces.

Well, that's ldap_int_search*(); let's vote for the "public" name. As I
said, I think it makes sense, since alias dereferencing has always been
explicitly required in the request.
OTOH, I have no objection to using a client-side control, as it wouldn't
add too much complexity (well, it'd require to parse a list of strings
with a worst-case of N * M, with N: number of known client controls; M:
client controls passed to the request), and it would pave the way for
client controls in libldap :) I see Hallvard already has a request for
another one.
One consideration: I'm not overlooking the value of not changing the API
too often; also, I fear client-side controls could be another way to
wind up with revitalizing the old API instead of designing a new one -
if anyone ever seriously considered the opportunity to design it.

Yes, the missing aliases argument is an API design bug. The API almost
but not quite has functions that match the protocol messages.
If we are going to export yet another search function, I'd like to see
another feature added as well: A way to pass the BER form of a filter
to the search function. And some helpers to build the BER form, and to
parse it back into the string form of a filter. Filters are complex
enough that it can be a pain to deal with the string form and its
quoting at times.
Of course, that one could be a client control too - e.g. combined with
passing NULL as the filter...

Hmm, maybe I missed something in this discussion and about the usage of
client controls.
But I'd vote for another function which provides a complete set of
arguments for sending search requests. So if ldap_search_ext is
considered incomplete regarding alias dereferencing I'd vote for
introducing ldap_search_ext2 (or whatever name) with an additional argument.
Ciao, Michael.
