Error description
"mod_ibm_ldap doesn't immediately retry LDAP connection on
unexpected error".

Applies to IHS 1.3.26, 1.3.28, 2.0.42, 2.0.47 and 6.0
Local fix Problem summary
mod_ibm_ldap caches connections to LDAP servers
to minimize connection establishment.  LDAP servers or LDAP
load balancers may drop the connection to mod_ibm_ldap at an
arbitrary time, such that when mod_ibm_ldap tries to use a
cached connection it will receive an I/O error.  Prior to this
APAR fix, mod_ibm_ldap would immediately return a 503 error to
the web browser when this occurred, and the end user would see
the error and have to decide what action to take.
Problem conclusion
mod_ibm_ldap will be changed with this APAR
fix to attempt to reestablish a connection to the LDAP server
when it receives an I/O error attempting to use a previously
cached LDAP connection.
If the connection was dropped by the server due to a timeout or
temporary problem, the reestablish attempt will succeed and the
503 error to the client will be avoided.
If the connection cannot be reestablished due to a more serious
problem with the network or LDAP server, the 503 error will
still be returned to the client.
