[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
In Section 5.1.2, “Default Access Logging Content”, 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. The entry op=-1 in the
access log 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.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 BIND dn="cn=Directory Manager" method=128 version=3
There are three possible bind method values:
• 0 for authentication
• 128 for simple bind with user password
• sasl for 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.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 BIND dn="cn=Directory Manager" method=128 version=3
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 Section 5.4, “LDAP Result Codes”.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
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.
