When defining a user ID in the system administration client,
follow the DB2® naming rules
if you want also want to use the ID for DB2 database
authentication.
You cannot use the following words for a user ID:
- USERS
- ADMINS
- GUESTS
- PUBLIC
- LOCAL
- Any SQL reserved word listed in the SQL Reference
You cannot begin a user ID with the following characters:
You can use the following characters for a user ID:
- A through Z
- 0 through 9
- #

- @
IBM® Content Manager supports the
following password characters across all client applications:
- All English letters, both uppercase and lowercase
- Numeric digits 0 through 9
- The space character
- The following characters: ! # $ % & ' ( ) * + ,
- . / : ; < = > ? @ ^ _
Tip: By default, the library server does not limit
the characters that users can enter for passwords. Even characters
that are not in the previous list can be entered, potentially creating
passwords that are incompatible between different client applications.
If you want to ensure that passwords are compatible across all clients
during password creation, use the ICMValidatePassword user exit.
Restrictions: - Some operating systems allow case-sensitive user IDs and passwords.
Check your operating system documentation to see if it allows for
case-sensitivity.
- The maximum length of the user ID is 30 characters, unless the
operating system imposes additional restrictions. Passwords are not
limited in length unless the operating system imposes additional restrictions.
- DB2 on Linux, AIX® or
Solaris: User IDs are limited to 8 characters.
- z/OS®: User IDs and
passwords are limited to 8 characters, or, if LDAP is used for authentication,
one to fifteen alphanumeric characters. Also one to fifteen alphanumeric
characters if any resource manager for this library server is on z/OS.
- If you grant specific database access authorities to a user ID,
a group can not exist that has the same name as that user ID.
