Characters that are valid for user IDs and passwords
Understanding character limitations for user IDs and passwords is important because they are used throughout IBM® Business Process Manager to provide access and secure content. The character limitations provided here apply to the IBM Business Process Manager administrator, the database administrator, the LDAP server administrator, and user IDs. Database and LDAP servers can have more restrictive limitations than provided here. Therefore you should check the database and LDAP server product documentation for restrictions. Failure to define user IDs and passwords correctly during the installation process can result in installation failure. In addition, your specific installation might have more restrictive user ID and password requirements that you must also follow.

User information | Valid characters | Unsupported characters |
---|---|---|
User ID |
|
Only ASCII characters are allowed. Other restrictions: The user ID cannot contain
spaces; for example, user name.
User IDs cannot be longer than 200 characters. If you enter any unsupported characters during the installation, you will receive an error message that states which character is invalid. For example, The special character [@] was found in the administrative user ID field. Enter the administrative user ID again. Avoid trouble: You
receive a different error message if you enter any unsupported characters
when creating users through the Manage users and groups portlet.

Password / Confirm password: | For bpm.cell.authenticationAlias: Lowercase characters {a-z} For all other user IDs: Lowercase characters {a-z} |
Diacritics, such as the umlaut, and DBCS characters
are not allowed. Other restrictions: The
password cannot contain spaces; for example, pass word.
Passwords cannot be longer than 128 characters. Avoid trouble: Login
or ConfigEngine tasks might fail if the password contains any unsupported
characters, including DBCS characters. This action happens even if
a user is successfully enrolled using a password containing DBCS characters.
If you enter any unsupported characters during the installation, you will receive an error message that states which character is invalid. For example, The special character [@] was found in the password field. Enter the password again. |
