Hi,

I use OpenLDAP C API for my LDAP client library and also OpenLDAP server for my tests (both of version 2.4.7). I am now working on unsolicited notification support. My code looks like this:

. . . struct timeval to; to.tv_sec = waitTime; to.tv_usec = 0;

LDAPMessage *res = NULL; SW_CHAR *retOid = NULL;

// // Check the notification // SW_INT32 rc = ldap_result(m_ldap, LDAP_RES_ANY, 1, &to, &res); . . .

My problem is that I always get timeout result code and NULL response message. To simulate the unsolicited notification, I use a retcode overlay with this configuration:

overlay retcode retcode-parent "ou=Example Codes,dc=example,dc=com"

retcode-item "cn=Unsolicited" 0x00 unsolicited="0" retcode-item "cn=Notice of Disconnect" 0x00 unsolicited="1.3.6.1.4.1.1466.20036"

To invoke it, I invoke search operation on "cn=Notice of Disconnect,ou=Example Codes,dc=example,dc=com". In slapd.log file, I can see something like this:

conn=2 op=1 SRCH base="cn=Notice of Disconnect,ou=Example Codes,dc=example,dc=com" scope=0 deref=0 filter="(objectClass=*)" conn=2 op=1 SRCH attr=objectclass send_ldap_extended: err=0 oid=1.3.6.1.4.1.1466.20036 len=0 send_ldap_response: msgid=0 tag=120 err=0 ber_flush2: 38 bytes to sd 12 0000: 30 24 02 01 00 78 1f 0a 01 00 04 00 04 00 8a 16 0$...x.......... 0010: 31 2e 33 2e 36 2e 31 2e 34 2e 31 2e 31 34 36 36 1.3.6.1.4.1.1466 0020: 2e 32 30 30 33 36 .20036 ldap_write: want=38, written=38 0000: 30 24 02 01 00 78 1f 0a 01 00 04 00 04 00 8a 16 0$...x.......... 0010: 31 2e 33 2e 36 2e 31 2e 34 2e 31 2e 31 34 36 36 1.3.6.1.4.1.1466 0020: 2e 32 30 30 33 36 .20036 conn=2 op=1 RESULT oid=1.3.6.1.4.1.1466.20036 err=0 text= daemon: activity on 1 descriptor daemon: activity on: 12r daemon: read activity on 12 daemon: select: listen=7 active_threads=0 tvp=NULL connection_get(12) connection_get(12): got connid=2 connection_read(12): checking for input on id=2 ber_get_next ldap_read: want=8, got=7 0000: 30 05 02 01 03 42 00 0....B. ber_get_next: tag 0x30 len 5 contents: ber_dump: buf=1005d4290 ptr=1005d4290 end=1005d4295 len=5 0000: 02 01 03 42 00 ...B. ber_get_next ldap_read: want=8, got=0

This looks like the server sent the notification. However, in my client library, I can't get it.

Can anyone help? Do I have wrong client code or is the problem in the way how I try to invoke the notification? I would appreciate any help.
