• What is the cause and solution for SAP error message LDAPRC087 - Filter string contains an error ?

  The SAP error message LDAPRC087, which states "Filter string contains an error," typically occurs when there is an issue with the LDAP (Lightweight Directory Access Protocol) filter string used in an LDAP query. This error can arise due to various reasons, such as syntax errors in the filter string, unsupported characters, or incorrect formatting.
  Causes:
  
  Syntax Errors: The filter string may contain typos or incorrect syntax that does not conform to LDAP filter standards.
  Unsupported Characters: Special characters in the filter string that are not properly escaped can lead to this error.
  Incorrect Logical Operators: Using logical operators (AND, OR, NOT) incorrectly can cause the filter to be invalid.
  Missing Parentheses: Parentheses must be balanced in LDAP filters; missing or extra parentheses can lead to errors.
  Invalid Attribute Names: Using attribute names that do not exist in the LDAP schema can also trigger this error.
  
  Solutions:
  
  Check Syntax: Review the filter string for any syntax errors. Ensure that it follows the correct LDAP filter syntax.
  
  Example of a valid filter: (&(objectClass=user)(sAMAccountName=jdoe))
  
  
  Escape Special Characters: If your filter string contains special characters (like *, (, ), \, etc.), ensure they are properly escaped.
  
  For example, to include a literal *, you would use \2a.
  
  
  Validate Logical Operators: Ensure that logical operators are used correctly and that the filter is logically sound.
  Check Parentheses: Make sure that all parentheses are balanced and correctly placed.
  Verify Attribute Names: Ensure that all attribute names used in the filter are valid and exist in the LDAP schema.
  Test the Filter: Use an LDAP browser or command-line tool to test the filter string independently to see if it works outside of SAP.
