This section lists the LDAP attributes to which the NDS attribute is mapped. If the attribute doesn't correspond to any LDAP attributes, this section won't exist on the page. The next piece of information on the page tells you which attribute syntax this attribute uses. I'll describe how to read this page in the next Directory Primer column. This section lists any constraints that apply to this attribute.
Attribute constraints are flags containing restrictions that affect an attribute value.
They can also impose constraints on NDS and NDS client operations. Allows for a single value or for multiple values Has a range or size limit to the value Is synchronized immediately, or at the next scheduled interval, or never Is hidden or is viewable Is writeable or is considered read-only The next five lists summarize the attribute constraints that you find listed in this section. These lists show only enough information to help you understand the listed attribute constraint. The following constraints regulate whether only servers can read the attribute, or whether clients can also read the attribute. Each attribute can have more than one constraint assigned to it.
