Re: (ITS#5731) Don't rewrite filter when it is undefined

The bug is confirmed; the proposed fix is incorrect, since it only addresses the case of a(n undefined) simple filter. A more complete fix (see also ITS#5732) is in HEAD, please test. p. Ing.

(ITS#5733) core dump in re24's slapd-ldap(5)

Full_Name: Pierangelo Masarati Version: re24 OS: Linux x86 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (81.72.89.40) Submitted by: ando I had a strange core dump while testing re24 (test039).

(ITS#5731) Don't rewrite filter when it is undefined

Full_Name: Kostantinos Koukopoulos Version: 2.4.11 OS: Solaris URL: ftp://ftp.openldap.org/incoming/kostantinos-koukopoulos-0811009.patch Submission from: (NULL) (195.134.100.30) When a client provides a search filter which turns out to be undefined (for example if the assertion value doesn't conform to the syntax) then the rwm overlay will try to map the value without knowing if it's normalized or not. In one case this caused an assertion failure.

I have included a patch which skips rewriting of a filter when it is undefined.

SIZELIMIT 0 gives a zero limit
by Fabio Pedretti 09 Oct '08

09 Oct '08

The ldap.conf man page says this: SIZELIMIT <integer> Specifies a size limit to use when performing searches. The number should be a non-negative integer. SIZELIMIT of zero (0) specifies unlimited search size. However it appears that putting "SIZELIMIT 0" in my ldap.conf gives a: # search result search: 2 result: 4 Size limit exceeded To workaround this I put a very large value and it works. I am using openldap 2.4.11 compiled from source on a Slackware 10.0. Is it an openldap bug? Thanks, Fabio
