Issue/Introduction

Starting CA LDAP, error message SECIN26E Bind failed, errno=1115, errno2=744C7247 pops up. What is the problem?

Environment

Component : CA LDAP Server for z/OS

Resolution

The errno=1115 means that something is already using the address/port combination, or your TCP/IP setup is restricting the use of the STC to the IP address/port. If DEBUG was turned on, the STDERR file could show something like this:

ldap_url_parse_ext(LDAP://:4389)
daemon: bind(6) failed errno=1115 (EDC8115I Address already in use.)
slap_open_listener: failed on LDAP://:4389

The following can be done to determine if the port is in use.

If the selected socket address/port is in the range INADDRANYPORT + INADDRANYCOUNT, then the
socket address/port is reserved. Change INADDRANYPORT + INADDRANYCOUNT or select a different
socket address/port for CA LDAP Server.

To determine if the socket address/port 4389 is in use, issue the TSO command netstat (po 4389).

If the socket address/port 4389 is available you will see the following:

netstat (po 4389)                                                           
MVS TCP/IP NETSTAT CS V1R12       TCPIP Name: TCPIP           13:18:33

  READY                                                                      
     
To determine if the socket address/port 389 is in use, issue the TSO command netstat (po 389).      

                                                                 
If the socket address/port 389 is in use something like this will see display output:  
     
netstat (po 389)
