Python LDAP converting objectGUID to hex string and back

How do I convert binary ldap attributes returned by python-ldap to a nice hex representation and back again for use in an ldap filter?

Solution 
  • def guid2hexstring(val):
    s = ['\\%02X' % ord(x) for x in val]
    return ''.join(s)

guid = ldapobject.get('objectGUID', [''])[0] # 'Igr\xafb\x19ME\xb2P9c\xfb\xa0\xe2w'
guid2string(guid).replace("\\", "") # '496772AF62194D45B2503963FBA0E277'

#and back to a value you can use in an ldap search filter

guid = ''.join(['\\%s' % guid[i:i+2] for i in range(0, len(guid), 2)]) # '\\49\\67\\72\\AF\\62\\19\\4D\\45\\B2\\50\\39\\63\\FB\\A0\\E2\\77'

searchfilter = ('(objectGUID=%s)' % guid)
