Public bug reported:

I am running latest keystone from git (82ded4a) and am using keystone
configured with the LDAP and using user_enabled_emulation.

I get the exception "IndexError: string index out of range" when trying
to authenticate.

My research suggests that it's the commit that fixed bug 1340041 that
introduced this bug. Everything works when I revert the commit that
fixed that.

The problem is the following:

in line 1672 (keystone/common/ldap/core.py) for the patch for the above
bug the ldap.dn.str2dn array gets converted to a string which causes
naming_rdn to contain "[" and then I get an exception on line 1675
because the string has length one.
