Any opinions? ldap.conf: TLS_PROTOCOL_MIN <major>,<minor> C: struct ldap_tls_protocol { unsigned char major, minor; } val; val.major = 3; val.minor=0; ldap_set_option(ld, LDAP_OPT_TLS_PROTOCOL_MIN, &val); ? (I'm running out of time to get _something_ into Sendmail's local copy, at which point I'll just commit something there and have to leave you guys to hack whatever you get around into the official repository.)

(ITS#5661) contextCSN gets corrupted on the stand by mirror
by ali.pouya＠free.fr 19 Aug '08

19 Aug '08

Full_Name: Ali Pouya Version: 2.4.11 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (145.242.11.4) I think there is a documentation issue for OpenLdap 2.4.11 : The chapter 17.4.4 of the Admin Guide recommends configuring TWO sycrepl directives for each mirror side. If I do so, the contextCSN of the stand by mirror gets corrupted very easily. But if I confugure the mirrors with only ONE syncrepl directive it's OK. The test environment : I have a test directory with two mirrors A (sid=1) and B (sid=2) configured as recommended in the Admin's Guide, and a replica C connected to A. The directory contains 10 million objects, and I use the server A for writing 500 000 new ones. Very often and without any apparent reason the contextCSN in the memory of B gets suddenly corrupted while those of A and C are OK. In this situation the contextCSN of B gets stuck but B continues to receive data from A. The value of contextCSN in base 64 is : contextCSN: 20080727021429.070493Z#000000#000#000000 contextCSN:: +HYDCTA4MDIwMzM3MTguMzAwMTExWiMwMDAwMDAjMDAxIzAwMDAwMA== I note that only the part indicating the year (2008) is garbled. May be this part is handled differently ? At service shutdown B writes the corrupt contextCSN to the disk. At service startup B reads the corrupt contextCSN from the disk and begins to scan ALL of the data base. Also it sends a sync request to A (a persitent search containing the corrupt contextCSN in the control field) causing A to scan the WHOLE data base. The replica C remains safe. If I reverse the roles of A and B the corruption occurs on A (always on the stand by mirror). I have already encountered the contextCSN corruption problem in OpenLdap 2.3 and this was one of my reasons to migrate to 2.4.11. Thanks for your HELP Best Regards Ali Pouya

(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

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/>
