Xlight FTP Server is an easy to use high performance FTP server with very low memory and CPU usage. It has many features and advanced features such as remote administration, SSL, SFTP,ODBC, LDAP, Active Directory, e-mail notification, and IPv6 support.
What's new in this version:
Version 3.8.6: Adds SHA-256 support for SSH transport of SFTP. Makes a change so that when mapping a user's AD groups to local FTP groups in Active Directory Authentication, the user's Primary Group in the AD will be checked first. Fixed a bug that when using other public key files list for SFTP public key authentication, only last public key file can work.
