I am using Spring-Ldap's LdapTemplate to create the connection between client and the LDAP server providing the custom socket factory with the key-manager which includes client-certificate and trust-store which includes server certificate. Hitting the below exception:

Caused by: javax.naming.NamingException: [LDAP: error code 1 - 00000000: LdapErr: DSID-0C09125A, comment: TLS or SSL already in effect, data 0, v3839]

Didn't find any concrete answer to the problem. Any suggestion would be appreciated.
