Tenant can be created with name more than 64 characters in length

I assume this is dependent on the backend driver, and this issue probably only applies to SQL?

Unmesh - could you reply with a note about what back-end you were using to be able reproduce this issue?

Also - perhaps a dummy question - why is a tenant with a name > 64 characters an issue or error?

I reproduced this issue using the SQL backend (identity driver = keystone.identity.backends.sql.Identity).
Error should be returned on (creating a tenant with name more than 64 characters in length) because the value stored in database is truncated (also, the API user does not know about the value being truncated).
Current implementation will return a 409 Conflict, if the first 64 characters of two tenant names are same.
