Bind Rules
Chapter 6 Managing Access Control 217
Using the userattr Keyword With Inheritance
When you use the
userattr
keyword to associate the entry used to bind with the
target entry, the ACI applies only to the target specified and not to the entries
below it. In some circumstances, you might want to extend the application of the
ACI several levels below the targeted entry. This is possible by using the parent
keyword, and specifying the number of levels below the target that should inherit
the ACI.
When you use the
userattr
keyword in association with the
parent
keyword, the
syntax is as follows:
userattr = "parent[
inheritance_level
].
attrName
#
bindType
"
or, if you are using an attribute type that requires a value other than a user DN,
group DN, role DN, or an LDAP filter:
userattr = "parent[
inheritance_level
].
attrName
#
attrValue
"
where
:
•
inheritance_level
is a comma separated list that indicates how many levels below
the target will inherit the ACI. You can include five levels
[0,1,2,3,4]
below
the targeted entry; zero (0) indicates the targeted entry.
•
attribute
is the attribute targeted by the
userattr
or
groupattr
keyword.
• bindType can be one of
USERDN,GROUPDN,LDAPURL
.
For example,
userattr = "parent[0,1].manager#USERDN"
This bind rule is evaluated to be true if the bindDN matches the manager attribute
of the targeted entry. The permissions granted when the bind rule is evaluated to
be true apply to the target entry and to all entries immediately below it.
Example With userattr Inheritance
The example in Figure 6-1 indicates that user
bjensen
is allowed to read and
search the
cn=Profiles
entry as well as the first level of child entries which
includes
cn=mail
and
cn=news
, thus allowing her to search through her own mail
and news IDs.
