Re: bug searching for 'attr==+=' (ITS#267)

[Kurt@OpenLDAP.org]

I have not been able to duplicate this issue.

I added the following entry to slapd running with
tests/data/slapd-master.conf and test.ldif loaded:

dn: cn=bug, o=University of Michigan, c=US
cn: bug
sn: =+=
description: test =+= for *=+= =+=* and *=+=*
objectclass: person
objectclass: top

I used 'sn' instead of 'badsearch' so as not to violate schema rules.

I then issued:

ldapsearch -L -p 9009 -b "o=University of Michigan, c=US" 'sn==+='
ldapsearch -L -p 9009 -b "o=University of Michigan, c=US" 'sn=*=+='
ldapsearch -L -p 9009 -b "o=University of Michigan, c=US" 'sn==+=*'
ldapsearch -L -p 9009 -b "o=University of Michigan, c=US" 'sn=*=+=*'
ldapsearch -L -p 9009 -b "o=University of Michigan, c=US" 'description=*=+=*'

and all returned:

dn: cn=bug, o=University of Michigan, c=US
cn: bug
sn: =+=
description: test =+= for *=+= =+=* and *=+=*
objectclass: person
objectclass: top
creatorsname: cn=Manager, o=University of Michigan, c=US
createtimestamp: 19990822060045Z

as expected.  I then remove the 'sn' index slapd-master.conf,
rebuild the database, and retested with same results.

Are you sure you properly protected the '*' from your command
shell?
