- Symptom:
In the main configuration file of OpenLDAP (slapd.conf), set the following configuration:
index_substr_if_minlen 100 index_substr_if_maxlen 5
Then, everything is fine. The system behaves as expectation. However, if reverse the order of the two configuration line as follows:
index_substr_if_maxlen 5 index_substr_if_minlen 100
Then, the system refused to start, with the following misleading message:
Mar 25 21:29:18 tianyin-desktop slapd[12700]: /home/tianyin/openldap-2.4.30/etc/openldap/slapd.conf: line 1: <index_substr_if_minlen> invalid value (5)
Unable to reproduce this symptom. In both cases I get
testrun/slapd.1.conf: line 31: <index_substr_if_minlen> invalid value (100)
Closing this ITS.
- Root cause in terms of code snippet
(1) servers/slapd/slap.h
#define SLAP_INDEX_SUBSTR_IF_MINLEN_DEFAULT 2 #define SLAP_INDEX_SUBSTR_IF_MAXLEN_DEFAULT 4

unsigned int index_substr_if_minlen = SLAP_INDEX_SUBSTR_IF_MINLEN_DEFAULT; unsigned int index_substr_if_maxlen = SLAP_INDEX_SUBSTR_IF_MAXLEN_DEFAULT;

It's quite clear that the order matters, and this should be a bug related to configuration.
Thanks, Tianyin
