Starting from BIG-IP 11.6.0, session variables may have modifiers when used in configuration, such as: %{session.logon.last.ldap.dn:ldapdn} With session variable modifier "ldapdn", the resultant value should be escaped by LDAP DN rules. The rules include an equals (=) character which should be escaped, but it is not.
Depends on the purpose of usage session variable with "ldapdn" modifier in a configuration.
LDAP session variable that contains LDAP DN is used in configuration with "ldapdn" session variable modifier.
It is possible to escape '=' character using the Variable Assign agent before using that session variable with the modifier in other configurations.
Now the session variable modifier "ldapdn" escapes the equal sign (=) character as well as other characters that require escaping.
