You can define the rules around building identifiers for new users in ADAM. The rules are set up by role or roles so you can define one set of rules for the student role and another set for the teacher role.
- Go to System > Client Settings.
- Click the General Settings tab.
- In the Restrict Identifiers for Role dropdown, select the role (or All Roles) you want to define rules for.
- Enter the User Identifier Pattern. For example, if you want to ensure all student identifiers are 11 digits long and start with either an A or a B, the pattern definition would like this: ^(A|B)[\d]{10}$
- Use the Anchor ^ to start the string.
- Use Quantifiers & Alternation (A|B) to specify the first character is either an A or B.
- Use Character Class [\d]{10} to specify a total of 10 additional digits.
- Use the Anchor $ to end the string.
- See the tables below for more possibilities.
