I'm not sure how you're building your modlist, but you might want to
using ldap.modlist: (example off the top of my head, may have typos)

import ldap
import ldap.modlist
import copy

l = ldap.initialize('ldap://server')
l.bind_s('...', 'pass')
dn, attrs = l.search_s(dn, ldap.SCOPE_BASE)

newattrs = copy.deepcopy(attrs)
newattrs['objectClass'].append('newobjectclass')
newattrs['cn'] = ('cn_value',)

mlist = ldap.modlist.modifyModlist(attrs, newattrs)
l.modify_s(dn, mlist)
