## Linux find file by content
# for example
find . -type f -name '*.java' -print0 | xargs -0 grep -l 'implements MyInterface'

## LDAP JXplorer trust self signed certificate
2 easy steps:

1) echo -n | openssl s_client -connect AD_SERVER:AD_SERVER_PORT | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ldapserver.pem
