Note: Should specify explicitly what has to be supported.

An overlapping requirement exists (with examples of LDAP, TACACS+, ...). To be checked later on if this-one can be omitted.

The new requirements proposed by Karin in comments: consider to add as new requirements, after checking that none of those are not already included.
