class useridresolver.PasswdIdResolver.IdResolver

Bases: useridresolver.UserIdResolver.UserIdResolver

checkDescription(line, pattern)

checkEmail(line, pattern)

checkPass(uid, password)

This function checks the password for a given uid. - returns true in case of success - false if password does not match

We do not support shadow passwords at the moment. so the seconds column of the passwd file needs to contain the crypted password

check for the userId

checkUserName(line, pattern)

check for user name

getConfigEntry(config, key, conf, required=True)

classmethod getResolverClassType()

getResolverDescriptor()
