Note the realm="Zope" above. You should add a password for such exact realm, or use an HTTPPasswordMgrWithDefaultRealm instead.
Also, the uri argument to add_password is wrong. Try this:

protocolo='http://'
servidor='10.28.1.239'
pagina='/manage'
fullurl=protocolo+servidor+pagina

aut=urllib2.HTTPBasicAuthHandler()
aut.add_password(realm="Zope",
                  uri=servidor,
                  user='myadmin',
                  passwd='mypass')
opener=urllib2.build_opener(aut, urllib2.HTTPHandler(debuglevel=1))
print opener.open(fullurl).read()

The other alternative would be:

pmgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
pmgr.add_password(None, uri=servidor, user=..., passwd=...)
aut = urllib2.HTTPBasicAuthHandler(pmgr)
opener=urllib2.build_opener(aut, urllib2.HTTPHandler(debuglevel=1))
