No. Read RFC4523.

After a lot of reading and testing I still cannot get it working.

I read RFC4523 and am now doing an ldap search of (usercertificate:**
certificateExactMatch:=**certificate_serial_number$**

certificate_Issuer_DN)
Than I get an (?=undefined) in my logfile, so the query is not correct.
In my schema is 2.5.4.36 and 2.5.4.37 defined.

When I search on

(usercertificate=certificate_**serial_number$certificate_**Issuer_DN)

I see the query in the log so I asume it is ok, but in the debugging i see
"illegal value for attributeType usercertificate"

Here's what I use:

'userCertificate={ serialNumber <yourserial>, issuer "<yourIssuerDN>" }'

For example:
'userCertificate={ serialNumber 5090, issuer "cn=passport country signing
authority, ou=ptb, ou=dfat, o=gov, c=au" }'

Thanks alot for pointing me in the right direction,

The search is working now.
Now I also noticed that I put in the serialnumber in Hex instead of decimal.
That is what I was doing wrong :-(
