Hello Andreas,

The mechanisms page enumerates the various authentication protocols supported by Dovecot, and mentions that each of these mechanisms may be used with a password stored as plaintext or using a mechanism-specific scheme (storage).

On the other hand, the schemes page enumerates various ways for storing passwords implemented by Dovecot, and relates each of those schemes to the mechanism(s) that may make use of it.

So, I would be tempted to speak about cross-references, not exactly about a repeat.

> This section lists one more mechanism, LANMAN.

Well, my understanding is that there was the LANMAN protocol (the mechanism) that used the LANMAN hash (the scheme). Later, that hash has been used for the NTLMv1 protocol as well.

> Can somebody explain why this section is in this file? And which of the two is applicable.

Yes, perhaps could the section title "Non-plaintext authentication mechanisms" be changed into something like "Password schemes specific to non-plaintext mechanisms".
