5.1. Introduction to user management in Nubus

This section provides some generic information that applies to various areas in the user management.

5.1.1. User account types

Nubus knows the following different types of user accounts:

Normal user accounts

These user accounts have all available properties. Users with such a user account can sign in to Nubus, or Windows systems and, depending on the configuration, also to the other third party services and applications. You can administer these user accounts through the Users management module. For more information, see Users module.

Address book entries

You can use address book entries to maintain internal or external contact information. Users can’t sign in through contacts entries to Nubus, or Windows systems. You can manage address book entries through the Contacts management module. For a reference, see Contacts module.

Simple authentication account

With such an account, Nubus creates a user object that has only a username and a password. With this account, only authentication against the LDAP directory service is possible, but no sign-in to Nubus or Windows systems. You can manage the accounts through the LDAP Directory management module.

5.1.2. Recommendation for username definition

The attribute username is an important and required attribute for user accounts. To avoid conflicts with the different tools handling user accounts in Nubus, you need to adhere to the following recommendations for the definition of usernames:

• Only use lower case letters (a-z), digits (0-9) and the hyphen (-) from the ASCII character set for usernames.

• The username starts with a lower case letter from the ASCII character set. The hyphen isn’t allowed as last character.

• In Nubus the username has at least a length of 4 characters and at most 20 characters.

The recommendation results in the following regular expression: ^[a-z][a-z0-9-]{2,18}[a-z0-9]$.

Besides the recommendation, in practice, usernames also contain underscores (_) and upper case ASCII letters. Consider the recommendation as a guideline and not a rule and keep potential side effects in mind when defining usernames outside the recommendation.
