A process executed multiple suspicious LDAP search queries.
This may be indicative of LDAP enumeration.

Check if the process executes LDAP search queries as part of its normal behavior.
Investigate the LDAP search query for any suspicious indicators.
Determine whether the search query is generic. Generic search queries (often using wildcards) tend to be more suspicious.
