Allowed characters
Usernames and passwords may consist of only:
abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890 _ . ! ~ * ' ( ) , "
- Spaces are allowed, but leading and trailing spaces will be trimmed.
- As with all HTML display in RPM, consecutive spaces in usernames will only be shown as a single space on the page.
- All illegal characters are stripped.
- All character stripping occurs before length is checked (see below).
[edit]
Length
- Usernames must be from 1 to 64 characters long (inclusive).
- Passwords must be from 6 to 64 characters long (inclusive).
[edit]
Unique
- Usernames must be unique among across all the users in a deployment.
- Passwords do not have to be unique.
[edit]
Case
- Usernames are case insensitive.
- Usernames are always saved and displayed in all lowercase.
- Example: You can't have both a "Jade" user and a "jade" user in the same deployment.
- Passwords are case sensitive.
- Example: "mypassword" will not get you in if the password is "myPASSword"
[edit]
Password display
- When creating a user the password is entered in plain text.
- When entering a password to logon or change a password, the characters are hidden.
- A password in the database is otherwise never displayed.
- In fact it can't be since it is only stored as a one-way hash. This is why a lost password must be replaced with a new one, and we can't just tell someone what their password is.
[edit]
History
- The user and logon infrastructure was among the first parts of RPM to be built.
- Wolf: Username and password limit increased from 24 to 64.
- May 31, 2006 hotfix: Many characters added and username and password character list made the same. One reason was to make any valid email address (64 characters or shorter) eligible for use.
