Novell eDirectory 8.8 Troubleshooting Guide - NetIQ

10.1.2 Step 2: Rectify the Error LDIF File to Eliminate the Errors
• Sun ONE defines some schema definitions publicly that eDirectory does not. This includes
attributes like, “objectClasses”, “attributeTypes”, “ldapSyntaxes” and “subschemSubentry”.
These definitions exist internally and are very important to the schema, and therefore, they
cannot be modified. Operations that try to modify these definitions results in the following
error:
novdocx (en) 22 June 2009
LDAP error : 53 (DSA is unwilling to perform)
Any records that contain references to these definitions cause the following error:
LDAP error : 16 : ( No such attribute )
Thus, records that contain any reference to these objects or that try to modify these definitions
need to be commented in the LDIF error file (err.ldf in the example).
• Some objectClasses definitions in Sun ONE do not have naming attributes. Adding these
objectClasses would result in the following error in eDirectory:
LDAP error : 80 (NDS error: ambiguous naming (-651)
This error occurs because Sun ONE does not use the same method for determining naming
rules as eDirectory.
To solve this, you can use any one of the three following options:
Option 1:
Go through each of the offending objectClasses and add a valid naming attribute to each of
them.
For example:
To add the naming attribute [ cn ] to the objectclass “netscapeMachineData” modify the entry
(that is emphasized in the example below) in the err.ldf file to include the X-NDS_NAMING
flag as shown below:
dn: cn=schemachangetype: modifyadd: objectClassesobjectClasses: (
2.16.840.1.113730.3.2.32 NAME ’netscapeMachineData’
DESC ’iPlanet defined objectclass’ SUP top STRUCTURAL MAY ’cn’ X-
NDS_NAMING ’cn’ )-
Option 2:
Go through each of the offending objectClasses and make them AUXILIARY or ABSTRACT.
For example:
To modify the objectclass definition of objectclass “netscapeMachineData” from
“STRUCTURAL” to “AUXILIARY”, modify the err.ldf file entry (that is emphasized in the
example below) as shown below:
dn: cn=schemachangetype: modifyadd: objectClassesobjectClasses: (
2.16.840.1.113730.3.2.32 NAME ’netscapeMachineData’
DESC ’iPlanet defined objectclass’ SUP top AUXILIARY )-
To modify the objectclass definition of objectclass “netscapeMachineData” from
“STRUCTURAL” to “ABSTRACT”, modify the err.ldf file entry (that is emphasized in the
example below) as shown below:
dn: cn=schemachangetype: modifyadd: objectClassesobjectClasses: (
2.16.840.1.113730.3.2.32 NAME ’netscapeMachineData’
DESC ’iPlanet defined objectclass’ SUP top ABSTRACT )-
