--- Comment #3 from Mehmet gelisin mehmetgelisin@aol.com --- Notice the [implicitly] tagged outer SEQUENCE. In your BER data, that additional tag seems to be missing and default tag for SEQUENCE type is used instead. http://www-look-4.com/
If you modify the original pyasn1 grammar for SearchResultEntry object to match your BER data (but not the standard!), pyasn1 decoder succeeds.
from pyasn1_modules.rfc2251 import SearchResultEntry http://www.compilatori.com/ from pyasn1.type.univ import Sequence from pyasn1.codec.ber import decoder ber = '0c\x043cn=Samba Unix UID
http://www.wearelondonmade.com/ Pool,ou=Testing,dc=stroeder,dc=de0,0\x14\x04\tuidNumber1\x07\x04\x05100050\x14\x04\tgidNumber1\x07\x04\x0510005'
SearchResultEntry.tagSet
http://www.jopspeech.com/ TagSet(Tag(tagClass=64, tagFormat=32, tagId=4)) # the following statement will invalidate SearchResultEntry grammar!
SearchResultEntry.tagSet = univ.Sequence.tagSet http://joerg.li/ SearchResultEntry.tagSet
TagSet(Tag(tagClass=0, tagFormat=32, tagId=16))
searchResultEntry, _ = decoder.decode(ber,asn1Spec=SearchResultEntry()) print searchResultEntry.prettyPrint() http://connstr.net/
SearchResultEntry: objectName='cn=Samba Unix UID Pool,ou=Testing,dc=stroeder,dc=de' attributes=PartialAttributeList: Sequence: type='uidNumber' vals=SetOf: '10005' http://embermanchester.uk/ Sequence: type='gidNumber' vals=SetOf: '10005'
Therefore my impression is that OpenLDAP yields incorrect BER data for SearchResultEntry object. What do you think?

I'd like to decode a LDAPv3 control value returned by OpenLDAP 2.4.25 when Pre-Read-Control was sent along with a LDAP modify request. But decoding it does not work.
Short example:
from pyasn1_modules.rfc2251 import SearchResultEntry from pyasn1.codec.ber import decoder ber = '0c\x043cn=Samba Unix UID
Pool,ou=Testing,dc=stroeder,dc=de0,0\x14\x04\tuidNumber1\x07\x04\x05100050\x14\x04\tgidNumber1\x07\x04\x0510005'
decoder.decode(ber,asn1Spec=SearchResultEntry())
Traceback (most recent call last): File "<stdin>", line 1, in <module> http://www.acpirateradio.co.uk/ File "/usr/local/lib/python2.6/site-packages/pyasn1-0.0.13a-py2.6.egg/pyasn1/codec/ber/decoder.py", line 663, in __call__ '%s not in asn1Spec: %s' % (tagSet, repr(asn1Spec)) pyasn1.error.PyAsn1Error: TagSet(Tag(tagClass=0, tagFormat=32, tagId=16)) not in asn1Spec: SearchResultEntry() https://waytowhatsnext.com/
