+ *
+ *  This function checks the collection of LDAPClient connections held by the

+ *  "domainName". The string may include a port number: e.g., "betty.nist.gov"

+ *  stored at "pClient". Otherwise, an LDAPClient is created and added to the
+ *  collection, and then stored at "pClient".
+ *
+ * PARAMETERS:
+ *  "aiaMgr"
+ *      The AIAMgr whose LDAPClient connected are to be managed. Must be
+ *      non-NULL.
+ *  "domainName"
+ *      Address of a string pointing to a server name. Must be non-NULL.
+ *      An empty string (which means no <host> is given in the LDAP URL) is
+ *      not supported.
+ *  "pClient"
+ *      Address at which the returned LDAPClient is stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns an AIAMgr Error if the function fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.
