Identity Synchronization for Windows allows you to create parameterized default values for creation 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 default values, follow these guidelines:
You can use multiple attributes in a creation expression (cn=%givenName% %sn%), but the attributes in % attribute_name% must have single values.
If A=0, 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, sn=%uid% and uid= %sn%).
