here is a mysql checker i made, probably not the best job but you can fix it :) from twisted.python import components, failure, log from twisted.cred import error, credentials from twisted.cred.checkers import ICredentialsChecker from twisted.enterprise import adbapi class MysqlPasswordDatabase : __implements__ = ICredentialsChecker credentialInterfaces = (credentials.IUsernamePassword,credentials.IUsernameHashedPassword) def __init__(self,db_name,db_username,db_password,table_name) : self.db_name=db_name self.db_username=db_username self.db_password=db_password self.table_name=table_name self.dbpool = adbapi.ConnectionPool("MySQLdb",host="localhost", db=db_name, user=db_username, passwd=db_password) def _dbResult(self,result,credentials) : #print result[0][0] #print credentials if result : if credentials.checkPassword(str(result[0][0])) : return credentials.username else : #print "Failing in password cmp" return failure.Failure(error.UnauthorizedLogin()) else : #print "Failing in dbresult" return failure.Failure(error.UnauthorizedLogin()) def _dbError(self,reason) : return failure.Failure(error.UnauthorizedLogin()) def requestAvatarId(self,c) : print "requestAvatarID ",c d=self.dbpool.runQuery("SELECT pword FROM %s WHERE uname = '%s'" % (self.table_name,c.username)) d.addCallback(self._dbResult,c) d.addErrback(self._dbError) return d anyway you get the idea, the above code works for me, but it assumes passwords are stored in plain text.
