About this task

idsldapsearch -b cn=schema -s base objectclass=* objectclasses

To change an object class using the command line, issue the following command:

idsldapmodify -D <adminDN> -w <adminPW> -i <filename>

where <filename>contains:

dn: cn=schema
changetype: modify
replace: objectclasses
objectclasses: ( <myobjectClass-oid> NAME '<myObjectClass>' DESC '<An object class 
I defined for my LDAP application>' SUP '<newsuperiorclassobject>'
<newobjectclasstype> MUST (<attribute1> $ <attribute2>) 
MAY (<attribute3> $ <attribute4>) )

Note: Modify-replace requests directed at the "cn=schema" entry have a special behavior that is not true for other entries. Normally a modify-replace replaces all values of the specified attribute, with the set of new values specified in the modify operation. However, when applied to the schema, only the referenced value is replaced. If this was not the case, this example would replace the definition of "myObjectClass", but also delete the definitions of all other objectclasses. The same behavior is true for modify-replace operations to replace attributetypes values.
