Subject: Assistance Needed with OTP Plugin Development

[TheBest Rodger]

Dear Support Team,

I hope this message finds you well. My name is Dmitry, and I am currently
developing an OTP plugin using kdctest and otp_state .  I am encountering
an issue during the development process, particularly after attempting to
log in on Ubuntu via the console with sudo login [username] and entering
the password.

The functions otp_init, otp_fini, otp_flags, and otp_edata are successfully
loaded and generate messages in com_err. However, I am facing a problem
with otp_verify, which does not loaded and does not print messages..
Despite trying various approaches to resolve this, I have not been
successful.

Additionally, I have used preauth modules: test and otp. Could the issue be
related to missing or incorrect configurations in kdc.conf or krb5.conf?
Perhaps there is something additional that needs to be included or
configured beyond what I have already implemented.

Your guidance on how to overcome this challenge would be greatly
appreciated.

Thank you for your time and assistance.

Best regards,

Dmitry
