Chapter 5 Access Log and Connection Code Reference 213
Slot Number
The slot number, in this case
slot=608
, is a legacy part of the access log which has
the same meaning as file descriptor. Ignore this part of the access log.
Operation Number
To process a given LDAP request, Directory Server will perform the required series
of operations. For a given connection, all operation request and operation result
pairs are given incremental operation numbers beginning with
op=0
to identify the
distinct operations being performed. In Code Example 5-1, on page 211, we have
op=0
for the bind operation request and result pair, then
op=1
for the LDAP search
request and result pair, and so on. Should you see
op=-1
in the access log, it
generally means that the LDAP request for this connection was not issued by an
external LDAP client but, instead, initiated internally.
Method Type
The method number, in this case
method=128
, indicates which LDAPv3 bind
method was used by the client. There are three possible bind method values:
•
0
= no authentication
•
128
= simple bind with user password
•
sasl
= SASL bind using external authentication mechanism
Version Number
The version number, in this case
version=3
, indicates the LDAP version number
(either LDAPv2 or LDAPv3) that the LDAP client used to communicate with the
LDAP server.
Error Number
The error number, in this case
err=0
, provides the LDAP result code returned from
the LDAP operation performed. The LDAP error number
0
means that the
operation was successful. For a more comprehensive list of LDAP result codes, see
“LDAP Result Codes,” on page 221.
Tag Number
The tag number, in this case
tag=97
, indicates the type of result returned, which is
almost always a reflection of the type of operation performed. The tags used are the
BER tags from the LDAP protocol. Commonly used tags include:
•
tag=97
for a result from a client bind operation.
