Identity Synchronization for Windows allows you to create parameterized default values for attributes using other creation or significant attributes.
To create a parameterized default attribute value, you embed an existing creation or significant attribute name— preceded and followed by percent symbols (% attribute_name %) — in an expression string. For example, homedir=/home/%uid% or cn=%givenName% %sn%.
When you create these attribute values:
You can use multiple attributes in a creation expression (cn=%givenName% %sn%).
If A=0, then B can have one default value only.
You can use the backslash symbol (\\) for quoting (for example, diskUsage=0\\%).
Do not use expressions that have cyclic substitution conditions (for example, if you specify description=%uid%, you cannot use uid=%description%..)
When Group Synchronization is enabled, the following are important:
The creation expression supported at Active Directory is cn=%cn%.
The creation expression must contain valid attribute names belonging to the group objectclass also since the creation expression is common to both user as well as the group.
For example: The attribute sn is not part of the groupofuniquenames objectclass at the Directory Server. Hence the following creation expression would be invalid for a group object. (Though it would work fine for user.)
The attribute used in the creation expression must be provided with a value for every user/group entry created. The value maybe provided using the command line interface, if the console does not have the provision.
