Main Settings / General Settings / Security Settings / External Sync / Append a suffix to the username account (usually used in multi-institutes configuration)
In case of multiple institutes (e.g. a district or a group of schools) with one tenant (Classter single URL or single Office365 tenant or one Google App Domain), we may have the following problem: Two users from two different institutes may have the same username (e.g.m.thomson@schooldisctritname.classter.com).
In order to avoid this common problem, we suggest the following username format: username.suffix@schooldisctritname.classter.com.
It is common that the suffix is the name of the institute.
For example, username.schoolname@myschool.classter.com However, in this setting you can freely set any suffix you prefer for the particular institute you configure.
Setting -> Active
E.g. Suffix = mysuffixTest
New username for users will be e.g., ttest.mysuffixTest@beta.classter.com
Setting -> Inactive
Username is without suffix
