Hi,

Does anyone already succeed to use VLV search requests through JNDI API ? It is functional with ldapsearch, but I get the following error on JDK 1.5 :

javax.naming.NamingException [Root exception is com.sun.jndi.ldap.Ber$DecodeException: Encountered ASN.1 tag 2 (expected tag 10)]

After doing some network captures between different directories implementation, it seems that there is a BER encoding error on the VLV response error code :

Global VLV control response ASN1 dump (through openssl asn1parse) : 0:d=0 hl=2 l= 50 cons: SEQUENCE 2:d=1 hl=2 l= 24 prim: OCTET STRING :2.16.840.1.113730.3.4.10 28:d=1 hl=2 l= 22 prim: OCTET STRING 0000 - 30 14 02 01 00 02 02 00-aa 02 01 00 04 08 10 0a 0............... 0010 - 82 15 .. 0016 - <SPACES/NULS>

Included octet string VLV control response ASN1 dump : 0:d=0 hl=2 l= 20 cons: SEQUENCE 2:d=1 hl=2 l= 1 prim: INTEGER :00 5:d=1 hl=2 l= 2 prim: INTEGER :AA 9:d=1 hl=2 l= 1 prim: INTEGER :00 12:d=1 hl=2 l= 8 prim: OCTET STRING 0000 - 10 0a 82 15 .... 0008 - <SPACES/NULS>

According to latest VLV draft (seems to be version 4) in section 5.2, return type for error code (last 00 in this dump) must be an enumerated type (tag type 10). In OpenLDAP response, error code is encoded as an integer (tag type 2).

I suggest to fix this by changing ber_printf(..."{iii ... to ber_printf(..."{iie ... in sssvlv.c:198. Please find a sssvlv patch attached.
