RE: ACIs problem when allowing "read" but restricting "updates" in specific entries

Hi !

   First of all, thanks for the answers ;-))

   Yes, it is true, I had a mistake with the nomenclature. The fact is that the
problem is NOT (as far as I tested it) in the regular expressions I am using
(I also checked it tracing the slapd execution with the "-d 128" option ... an
checked the matching is ok).

  I find the problem with the "read" access privilege for "data1checker" user.

   "uid=data1owner" is able to read an modify attributes values in entries matching
this regular expression (it is ok) ... but it is exactely the same behaviour a 
"uid=data1checker" in spite this last one has ONLY read privileges (???)

   I interpreted (after reading manual pages and openldap-related FAQs) that "read"
privilege only allows to read (but NOT modify) attribute values for entries
matching the rule .. but it is NOT what I am getting ...

 Am I understanding "read" privilege worngly ?

Thanks in advance

P.S: I also tested with openLDAP3.2.8, but it is the same behaviour ... and I almost
sure the error is NOT in the regexp being used (I was testing it in deep to be sure
about that).

He was using ACLs.  He just called them ACI's.  You may want to read his entire email.
