• What is the cause and solution for SAP error message SLDAP_ICM110 - Host name (&1) contains more than one "*" (server &2) ?

  The SAP error message SLDAP_ICM110 indicates that there is an issue with the hostname configuration in the context of the Internet Communication Manager (ICM) when using LDAP (Lightweight Directory Access Protocol). The specific error message states that the hostname contains more than one asterisk ("*"), which is not allowed.
  Cause:
  The error occurs when the hostname specified in the configuration contains multiple asterisk characters. In DNS and hostname conventions, the asterisk is often used as a wildcard character, but having more than one asterisk in a hostname can lead to ambiguity and is not compliant with standard hostname rules.
  Solution:
  To resolve this error, you should check the hostname configuration in your SAP system and ensure that it adheres to the following guidelines:
  
  
  Review Hostname Configuration:
  
  Go to the relevant configuration settings where the hostname is defined (e.g., in the ICM settings or LDAP configuration).
  Look for any entries that contain multiple asterisks.
  
  
  
  Modify Hostname:
  
  Change the hostname to use a single asterisk if necessary, or remove the asterisk altogether if it is not needed.
  Ensure that the hostname is valid and follows the standard naming conventions (e.g., no special characters other than hyphens, and it should not start or end with a hyphen).
  
  
  
  Test Configuration:
  
  After making changes, save the configuration and restart the ICM or the relevant services to apply the changes.
  Test the connection to ensure that the error no longer occurs.
