The list of supported control in a LDAP directory is available in the rootDSE (entry with empty dn): To retrieve the list of supported control, do the following ldap search
ldapsearch ... -b "" -s base "objectclass=*" supportedControl
Thank you very much for your answer.
Can we control/extention information which is requested by client along with the LDAP operations.
I tried in access logs but couldn't find any information.
Thanks once again!
