Solve the following python programming problem given the following code:
def addAuth(self, hostmask) : 
    "Sets a user's authenticated hostmask.  This times out according to
        conf.supybot.timeoutIdentification.  If hostmask exactly matches an
        existing, known hostmask, the previous entry is removed." 
    if (self.checkHostmask (hostmask, useAuth = False) or (not self.secure)) : 
        self.auth.append ((time.time (), uniqued)) 
        knownHostmasks = set () 
        def uniqueHostmask(auth) : 
            (_, mask) = auth 
            if (mask not in knownHostmasks) : 
                knownHostmasks.add (mask) 
                return True 
return False 
uniqued = list (filter (uniqueHostmask, reversed (self.auth))) 
        self.auth = list (reversed (uniqued)) 
else : 
        raise ValueError ('secure flag set, unmatched hostmask') 

    
    

    Fix the buggy line: self.auth.append ((time.time (), uniqued))

#Here is Python program to fix the buggy line: self.

self.auth.append ((time.time (), hostmask))
