bugs found in Netscape LDAP JDK 4.17

[Liu, MingHui]

I could not decode the sub filter sent by Outlook which is hidden in a virtuallistcontrol requrest’s data section, using the library, as it throws IO exception: java.io.IOException             at netscape.ldap.client.JDAPBERTagDecoder.getElement(Unknown Source)             at netscape.ldap.ber.stream.BERTag.<init>(Unknown Source)             at netscape.ldap.ber.stream.BERElement.getElement(Unknown Source)             at netscape.ldap.ber.stream.BERConstruct.<init>(Unknown Source)             at netscape.ldap.ber.stream.BERSequence.<init>(Unknown Source)             at netscape.ldap.ber.stream.BERElement.getElement(Unknown Source)             at com.intraspect.ldap.server.LDAPVirtualListRequest.parseResponse(LDAPVirtualListRequest.java:109)             at com.intraspect.ldap.server.LDAPVirtualListRequest.<init>(LDAPVirtualListRequest.java:97)             at com.intraspect.ldap.server.LDAPConnection.processSearchRequest(LDAPConnection.java:379)             at com.intraspect.ldap.server.LDAPConnection.processResponse(LDAPConnection.java:156)             at com.intraspect.ldap.server.LDAPConnection.run(LDAPConnection.java:73)             at com.intraspect.util.ThreadPoolThread.run(ThreadPoolThread.java:73)   I figured out that the fix is something like this in class JDAPBERTagDecoder, method:       public BERElement getElement(BERTagDecoder decoder, int tag,         InputStream stream, int[] bytes_read, boolean[] implicit)   …             case 0x81:                 element = new BEROctetString(decoder, stream, bytes_read);       -> I added this part.                 implicit[0] = true;             break;             case 0x85:  /* Context Specific [5]:                  * (a) Handle Microsoft v3 referral bugs! (Response)                   -> some existing codes                  * (b) Handle Microsoft v3 supportedVersion in Bind                  *     response                             */                 element = new BERInteger(stream, bytes_read);                 implicit[0] = true;             break;    …   I am not 100% sure about this, and not sure if this is MS specific or it is a library bug, anybody can help??   Thanks a lot,   Ming Software Engineer Vignette Corporation Level 1 116 Miller Street North Sydney 2060   Phone:   +61 2 9455 5318 Fax:       +61 2 9455 5200 Mobile:  +61 402 317 053 minghui.liu@vignette.com Vignette's software and expertise help organizations harness the power of information and the Web to deliver measurable improvements in business efficiency.
