ldapsearch error

Dears

We are using RHEL 8 in our environment , and we are trying to query the domain controller via ldapsearch. The search fails with the below error:
2022-01-24 10:25:24,051, Level=ERROR, Pid=433757, File=search_command.py, Line=384, Abnormal exit: # host: dc: Could not access the directory service at ldap://dc:389: LDAPStrongerAuthRequiredResult - 8 - strongerAuthRequired - None - 00002028: LdapErr: DSID-0C09027F, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v3839 - bindResponse – None

Appreciate if somebody could assist us in this.
