class twisted.plugins.cred_unix.UNIXChecker: (source)
Implements interfaces: twisted.cred.checkers.ICredentialsChecker
A credentials checker for a UNIX server. This will check that an authenticating username/password is a valid user on the system.
Does not work on Windows.
Right now this supports Python's pwd and spwd modules, if they are installed. It does not support PAM.
| Class Variable | credentialInterfaces | A list of sub-interfaces of ICredentials which specifies which I may check. |
| Method | checkPwd | Obtain the encrypted password for username from the Unix password database using pwd.getpwnam, and see if it it matches it matches password. |
| Method | checkSpwd | Obtain the encrypted password for username from the Unix shadow password database using spwd.getspnam, and see if it it matches it matches password. |
| Method | requestAvatarId | Validate credentials and produce an avatar ID. |
A list of sub-interfaces of ICredentials which specifies which I may check.
Obtain the encrypted password for username from the Unix password database using pwd.getpwnam, and see if it it matches it matches password.
| Parameters | pwd | Module which provides functions which access to the Unix password database. (type: module) |
| username | The user to look up in the Unix password database. (type: unicode/str or bytes) | |
| password | The password to compare. |
Obtain the encrypted password for username from the Unix shadow password database using spwd.getspnam, and see if it it matches it matches password.
| Parameters | spwd | Module which provides functions which access to the Unix shadow password database. (type: module) |
| username | The user to look up in the Unix password database. (type: unicode/str or bytes) | |
| password | The password to compare. |
Validate credentials and produce an avatar ID.
| Parameters | credentials | something which implements one of the interfaces in credentialInterfaces. |
| Returns | a Deferred which will fire with a bytes that identifies an avatar, an empty tuple to specify an authenticated anonymous user (provided as twisted.cred.checkers.ANONYMOUS) or fail with UnauthorizedLogin. Alternatively, return the result itself. | |
