The importance of a …
In IdM, the smallest of detail makes the must enormous difference, as I found out today. On a to Identity store pass, you have a number of options to choose in the column, helpfully that has no heading.
The options are “.”, “@” and “#” and the one in particular that caught me out is the “.”
This means that the attribute is only written when the entry is created, and does not mean that the attribute is only written when the attribute is created as I had previously thought.
In our scenario we had an attribute we did not want to be overwritten and so we added a “.” to it. We then changed the sequence of 2 tasks and this resulted in a complete change of behaviour as the first pass no longer creates the identity.
So hopefully a useful explanation of the power of …
The column is usually referred to as the prefix column. The operators in here are incredibly powerful and useful. I believe there is a complete description in the help file.
If you have a value that you don't want overwritten, I would suggest just keeping it out of any modify tasks, or use the prefix operator "#" to comment them out.
Hope this helps!
I also like to use "." for objectclass and name attributes when writing to AD!
