7.3.2 User schema differences between Directory Server and Active Directory
Although Active Directory supports the same basic X.500 object classes as Directory Server, there
are a few incompatibilities of which administrators should be aware.
7.3.2.1 Values for cn attributes
In Directory Server, the cn attribute can be multi-valued, while in Active Directory this attribute
must have only a single value. When the Directory Server cn attribute is synchronized, then,
only one value is sent to the Active Directory peer.
What this means for synchronization is that,potentially, if a cn value is added to an Active
Directory entry and that value is not one of the values for cn in Directory Server, then all the
Directory Server cn values are overwritten with the single Active Directory value.
One other important difference is that Active Directory uses the cn attribute attribute as its
naming attribute, where Directory Server uses uid. This means that there is the potential to
rename the entry entirely if the cn attribute is edited in the Directory Server. If that cn change
is written over to the Active Directory entry, then the entry is renamed, and the new named
entry is written back over to Directory Server. This only happens, however, if the cn attribute is
synchronized. If the change is not synchronized, then the entry is not renamed.
7.3.2.2 Password policies
Both Active Directory and Directory Server can enforce password policies such as password
minimum length or maximum age. Windows Sync makes no attempt to ensure that the policies
are consistent, enforced, or synchronized. If password policy is not consistent in both Directory
Server and Active Directory, then password changes made on one system may fail when synched
to the other system. The default password syntax setting on Directory Server mimics the default
password complexity rules that Active Directory enforces.
