User template conditions

User template conditions

I'm trying to create a new user template with a condition that if there is a user with the existing name format to create, say, jdoe1 or j.doe instead of failing on trying to create jdoe again.

I found this link but can't find the section presented in the steps in ADMP. Please advise.
