search with a wildcard works, with exactly matching string it doesn't - openldap-technical

30 Jul 2015


      Hi
If I run a query against my directory with this filter:
"(myDeviceId=ZZZ-07430.08.12345678*)"
it returns a match showing precisely that myDeviceId =
"ZZZ-07430.08.12345678"
If I use this filter, without the wildcard and just the actual value
"(myDeviceId=ZZZ-07430.08.12345678)"
it returns no match.
Even if I change the attribute value to something very simple like "x" I
still need to include a wildcard in my filter to get any match.
This works however:
"(myDeviceId:caseExactMatch:=ZZZ-07430.08.12345678)"
What gives here?
The specific attribute is defined in the schema file as follows:
attributetype ( 1.3.6.1.4.1.36200.255.0.17
        NAME 'myDeviceId'
        DESC 'Identifies a device'
        SUP uid
        EQUALITY caseExactMatch
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15
        SINGLE-VALUE
 )
I am no expert, but this makes no sense to me?  I feel I am missing
something, but what?
I am using openldap on CentOS 6 and workign via command-line tools (e.g.
ldapsearch). The backend is mdb if that matters.
# rpm -qa | grep openldap

openldap-servers-2.4.39-8.el6.x86_64
Thanks for any ideas/suggestions.
Best,
