Before you start:
Before you can configure a message flow to perform identity authentication, you need to check that an appropriate security profile exists, or create a new security profile. See Configuring a security profile.
LDAP:
mqsisetdbparms -n LDAP -u username -p passwordor
mqsisetdbparms -n <servername> -u username -p passwordwhere <servername> is your base LDAP server name, for example, ldap.mydomain.com.
If the message identity does not contain enough information for authentication, the information must be taken from the message body. For example, if a password is required for authentication but the message came from MQ with only a username, the password information must be taken from the message body. For more information, see Configuring identity.
