I have a problem connecting via L2TP/Ipsec connection from a windows 7 client to a Linux VPN server, using PAP for authentication. I am using a special long password, which is 54 characters in length. The ipsec channel is establishing, but the login is failing, and the VPN Server logs indicate that the password is being truncated to only 48 characters. I am able to connect without problem when the password length is the 'normal' 12 or so characters, but I need to authenticate with this long password. Is there a 48 character limit to the password length accepted by the VPN client? Is there a setting, even registry setting, that I can change to increase this length? Thank you for any help.

This is the maxim length. Cannot be extended.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.

Thank you for your reply. Please treat this as one vote for an increase to the maximum password length in the Microsoft VPN Client!
