ldap.schema: str2objectclass() fails

[Michael Ströder]

HI!

ldap.schema.str2objectclass() fails when parsing the following 
string (from Netscape DS 4.16SP1 sub schema sub entry):

"( 2.5.6.1 NAME 'alias' DESC 'Standard ObjectClass' SUP 'top' MUST 
( objectclass $ aliasedObjectName )  MAY ( aci ) )"

This schema string does not look unusual to me but...

 >>> ldap.schema.str2objectclass("( 2.5.6.1 NAME 'alias' DESC 
'Standard ObjectClass' SUP 'top' MUST ( objectclass $ 
aliasedObjectName )  MAY ( aci ) )")
Error: 6:  MUST ( objectclass $ aliasedObjectName )  MAY ( aci ) 
)Traceback (most recent call last):
   File "<stdin>", line 1, in ?

Well, I'd like to see some better error reporting with the help of 
exceptions. Anyway, there is a debug output text "Error: 6: .." 
produced. Don't know whether by the OpenLDAP libs or some code in 
Modules/schema.c.

Hans, before I ask on the OpenLDAP list what this error means can 
you please review your code and test with the string above? Make 
sure to bring your CVS working tree in sync!

Ciao, Michael.
