Hi ! I have a doubt trying to code an "assertion control" (according to RFC 4528) in the "control" field of an LDIF file. The assertion to code is a simple "equalityMatch" filter (i.e. "attribute type = attribute value"). This is the LDIF file I was preparing (to pass to an "ldapmodify" command) # LDIF file START (it contains all the updates for a single/atomic LDAPModify op.): dn: <entry dn to update> control: 1.3.6.1.1.12 true :<controlValue> changetype: modify ... How do I code the "controlValue" (i.e. the equalityMatch filter describing the required assertion) in the LDIF file? I thought it was the BER encoding, but after reading the formal syntax definition for the control field in RFC 2849 (LDIF spec) it is not clear to me ...
