(ITS#5660) SHA-2 hash support
by jeff＠atlassian.com 18 Aug '08

18 Aug '08

Full_Name: Jeff Turner Version: 2.3.30 OS: Linux URL: http://confluence.atlassian.com/download/attachments/162431971/openldap-sha… Submission from: (NULL) (203.63.130.33) OpenLDAP currently supports MD5, CRYPT and SHA1 hash formats. I needed support for SHA-512, so I have created a module to support SHA512, and the other SHA-2 formats (SHA256 and SHA384). I'd be happy for it to be included in OpenLDAP's contrib/slapd-modules/passwd/ directory. Code suitable for inclusion is linked in the ticket URL, and there is a fuller description of its use in the included README, or at http://confluence.atlassian.com/display/JIRAEXT/OpenLDAP+support+for+SHA-2+… As for the code, it is a thin module wrapper on an unmodified version of the BSD-licenced sha2.{c,h} by Aaron Gifford: http://www.aarongifford.com/computers/sha.html This also appears to be the SHA2 implementation used by OpenBSD. Please let me know if you have any questions.

(ITS#5659) patch for collect overlay
by brett.maxfield＠gmail.com 17 Aug '08

Full_Name: Brett Maxfield Version: HEAD OS: Linux suse 2.6.22.18-0.2-xen #1 SMP 2008-06-09 13:53:20 +0200 x86_64 x86_64 x86_64 GNU/Linux URL: ftp://ftp.openldap.org/incoming/brett-maxfield-080817.tgz Submission from: (NULL) (220.245.180.135) Fixes bug with overlay system where it would inherit/collect attributes to the entry that was supplying those attributes, causing duplicate attributes in that node. Also add a alternate config format for easy entry, eg old format: overlay collect collectinfo <dn> <attribute> and now in addition to above also supports : overlay collect collectinfo <dn> <attribute1>,<attribute2>,<attributeN>

Here is a patch, untested alas because I don't have time at the moment to set up something with back-perl. It compiles. I'm not fully sure that the handling of embedded and argc is correct. Perl 5.10 (and some earlier versions) require calling some additional macros around Perl interpreter setup and shutdown. Not doing these calls causes problems on HPPA at least, and may affect other platforms in the future. This patch adds the additional code modelled on the perlembed man page and a working patch for INN.

It's a general change to the libperl API and may not only affect HPPA. You're apparently now required to call those macros, and in the future they may have more effects. What we did for INN was add: #ifdef PERL_SYS_INIT3 PERL_SYS_INIT3(&argc, &argv, &env); #endif before perl_alloc, #ifdef PERL_EXIT_DESTRUCT_END PL_exit_flags |= PERL_EXIT_DESTRUCT_END; #endif after perl_construct, and: #ifdef PERL_SYS_TERM PERL_SYS_TERM(); #endif after perl_free. See man perlembed; with Perl 5.10, its example now reads: int main(int argc, char **argv, char **env) { PERL_SYS_INIT3(&argc,&argv,&env); my_perl = perl_alloc(); perl_construct(my_perl); PL_exit_flags |= PERL_EXIT_DESTRUCT_END; perl_parse(my_perl, NULL, argc, argv, (char **)NULL); perl_run(my_perl); perl_destruct(my_perl); perl_free(my_perl); PERL_SYS_TERM(); } Notice that we don't use the "env" pointer. Normally handed to "perl_parse" as its final argument, "env" here is replaced by "NULL", which means that the current environment will be used. The macros PERL_SYS_INIT3() and PERL_SYS_TERM() provide system-specific tune up of the C runtime environment necessary to run Perl interpreters; since PERL_SYS_INIT3() may change "env", it may be more appropriate to provide "env" as an argument to perl_parse(). -- Russ Allbery (rra(a)stanford.edu) <http://www.eyrie.org/~eagle/>

(ITS#5658) slapo-perl symbol updates

Full_Name: Quanah Gibson-Mount Version: 2.4.11 OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (69.109.79.65) http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=495069 Not sure how much we care about hppa architecture. As described in the 'perlembed' document, programs embedding Perl must use the PERL_SYS_INIT3() and PERL_SYS_TERM() macros to provide system-specific tune up of the C runtime environment necessary to run Perl interpreters. Your package has been identified as failing this: - at least one of the binary packages built from the source depends on libperl5.10 - the unpacked source matches 'perl_parse' but not 'PERL_SYS_INIT3' As a consequence, the embedded Perl interpreter is most probably broken on the hppa architecture, where PERL_SYS_INIT3() is needed for initializing lock structures. Without this, calling perl_parse() will hang inside pthread_mutex_lock(). See #486069 for more information.

(ITS#5657) Broken symlinks in /etc/ssl/certs prevent ssl connection
by Martin.vGagern＠gmx.net 15 Aug '08

15 Aug '08

Full_Name: Martin von Gagern Version: 2.3.43 OS: Gentoo Linux URL: https://bugs.gentoo.org/show_bug.cgi?id=234816 Submission from: (NULL) (84.188.31.84) On systems with broken symlinks in the default certificate directory of openssl, I found it impossible to establish an ldaps connection with openldap. I originally reported this issue as https://bugs.gentoo.org/show_bug.cgi?id=234816 I first encountered this when I got informed by luma that I could not connect to a server. I then reproduced this on the command line: $ ldapsearch -H ldaps://ldap.domain.tld ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) $ ldapsearch -d 15 -H ldaps://ldap.domain.tld ... ldap_connect_timeout: fd: 3 tm: -1 async: 0 TLS: could not load client CA list (file:`',dir:`/etc/ssl/certs/'). TLS: error:0906D06C:PEM routines:PEM_read_bio:no start line pem_lib.c:647 ... previous line repeated 13 times ... TLS: error:02001002:system library:fopen:No such file or directory bss_file.c:356 TLS: error:20074002:BIO routines:FILE_CTRL:system lib bss_file.c:358 ldap_perror ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) Sadly it does not say what file can't be opened. The "no start line" errors seem to be non-fatal. The fopen error in bss_file.c from dev-libs/openssl on the other hand seems to cause the connection to fail. Root of the cause seemed to be several broken symlinks in /etc/ssl/certs. Steps to solve the issue by removing those links: # find /etc/ssl/certs -type l ! -xtype f ! -xtype d -ok rm -f {} \; Steps to reproduce the issue, provided you have an SSL-Enabled LDAP server: # ln -s bar.pem /etc/ssl/certs/foo.pem $ ldapsearch -d 15 -H ldaps://ldap.domain.tld Ideally openldap should trat these errors as non-fatal, the way s_client does, so that such a broken symlink won't prevent all connections. If that path towards solution proves infeasible (as the openssl function SSL_add_dir_cert_subjects_to_stack seems to behave this way and adding all files manually might be a pain), at least there should be some error message telling the user that the problem lies in the local SSL certificates setup, not really in the network connection or remote configuration. By the way, I'm using openssl version 0.9.8h.

Re: (ITS#5655) add option for setting minimum TLS/SSL protocol

As I mentioned in the ITS, I think treating the various protocol versions as independently choosable is a Bad Thing, as it permits broken settings with no corresponding gain. That said, it's more important to me that *some* option gets in so that I (and Sendmail) don't have to maintain forever a patch to add it. If someone 'official' will make a decision and simply state what the option should look like in its three forms (C API, ldap.conf, slapd config), I'll munge the patch to match. Philip Guenther

(ITS#5656) Bind operations with translucent overlay
by mateusz.kijowski＠gmail.com 14 Aug '08

14 Aug '08

Full_Name: Mateusz Kijowski Version: 2.3.43 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.126.222.22) In some use scenarios, it is useful if the translucent overlay does not forward bind operation requests to the remote server when there are values for userPassword attribute in the local database. It would be nice if this could be enabled or disabled by a configuration option. For consistency, enabling this behavior should also affect the PASSMOD extended operation to modify the local value of userPassword.
