(ITS#6055) Samba4 need 'name' implementation like AD (RDN-Name)
by abartlet＠samba.org 12 Apr '09

12 Apr '09

Full_Name: Andrew Bartlett Version: CVS HEAD OS: Fedora 10 URL: http://msdn.microsoft.com/en-us/library/cc223167(PROT.13).aspx Submission from: (NULL) (59.167.251.137) Active Directory always presents an attribute 'name' that is always equal to the relative distinguished name. AD allows only one RDN, but I don't mind if this can be multi-valued for the multi-RDN case. It is equal to the value of the RDN as presented in the RDN. This is not simply the subtype 'CN -> name', but a new attribute unrelated to the existing definition of 'name'. I don't care what name is assigned to 'name', as I can easily remap attributes. It would be great if this could be constructed such that it may be declared to be unique for a particular one-level search (also an AD requirement, but not one Samba4 requires or enforces at this time).

You SHOULD place additional schema files (not shipped with OpenLDAP) in a separate directory. You SHOULD NOT customize/tweak the schema files shipped with OpenLDAP. Ciao, Michael.

OK, a status file. It would record the old and new index masks for the attributes being reindexed, and the entryID where it stopped. If slapindex is run without a specific list of attributes, (reindex everything) it should remove and ignore the status file. If slapindex is run with a specific list of attributes, and those attributes are in the status file, it should use the saved status and remove the specified attributes from the status file. (Deleting the file if there are no other attributes remaining.) Otherwise, when slapd starts, it should read the status file and resume the indexing task. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

slap_sl_malloc( sizeof( struct berval ) * (i+1), ctx ); [...] keys[j].bv_val = NULL; keys[j].bv_len = 0; Looking back through the call chain, do_syncrepl() sets op->o_tmpmemctx to NULL: /* use global malloc for now */ op->o_tmpmemctx = NULL; op->o_tmpmfuncs = &ch_mfuncs; so generalizedTimeIndexer()'s call to slap_sl_malloc() falls back to ber_memalloc_x() due to the null ctx. If malloc() fails there, NULL is eventually returned to the original caller of slap_sl_malloc(), likely resulting in a segfault. All of the indexing routines seem to ignore slap_sl_malloc()'s return value, opening them up to this problem, too. Someone else will need to step in with a proper fix since I don't know much about slapd internals, but it seems that if these routines are being called with a deliberate null ctx, they should be checking for malloc failure. A cursory glance around back-bdb indicates that indexing function callers already handle failure return codes gracefully.

(ITS#6052) Small typo in SASL chapter (15) in administration guide
by kkalev＠gmail.com 10 Apr '09

10 Apr '09

Full_Name: Kostas Kalevras Version: 2.4 OS: FreeBSD URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (147.102.247.75) In OpenLDAP 2.4 Administration Guide, chapter 15 (Using SASL) in 15.3.3.1. Notes on Proxy Authorization Rules the documentation states that the administrator can use regular expression matching like: authzTo: dn.regex=^uid=[^,]*,dc=example,dc=com$ I believe the correct form should be: authzTo: dn.regex:"^uid=[^,]*,dc=example,dc=com$" Notice the : instead of = and the quotes around the regular expression.

(ITS#6051) JLDAP SASL issue
by hendrik.saly＠gmx.de 10 Apr '09

Full_Name: Hendrik Saly Version: JLDAP 4.3 OS: Linux 2.6, Sun JDK 1.5 URL: http://svn.muleforge.org/mule-transport-ldap/trunk/src/main/java/com/novell… Submission from: (NULL) (78.43.136.21) While trying to use SASL with JLDAP i encounter a potential minor bug in $OpenLDAP: pkg/jldap/com/novell/ldap/LDAPConnection.java,v 1.154 2006/02/09 08:43:45 sunilk Exp $ Seems the bind method on line 1730 fails to release the bind semaphore properly under some circumstances. I tried to use more than the wit JLDAP provided SASL mechanisms DIGESTMD5 and EXTERNAL by wrapping the novell sasl client with a Java 1.5 sasl client. All works very well but CRAM login for example fails. I have a workaround http://svn.muleforge.org/mule-transport-ldap/trunk/src/main/java/com/novell… but i thinks there are some problems with the bind semaphore. The wrapping code is here http://svn.muleforge.org/mule-transport-ldap/trunk/src/main/java/org/mule/t… If neccessary i can provide a test suite for this. Thanks Hendrik
