KB-3130: Error "client.sudo Unexpected error in conversation"

Auditing and Monitoring Service ,   Authentication Service ,   Mac & PC Management Service ,  

12 April,16 at 11:09 AM

Applies to: All versions of Centrify DirectControl
 
Question:

No error message appears in the terminal when running sudo command. 
 
However debug logs show "client.sudo Unexpected error in conversation" 

May  3 10:30:50 gbl03303 adclient[19085]: DEBUG <fd:25 sudo(17674)> client.sudo Prompt user for PAM_AUTHTOK: 'Password: '
May  3 10:30:51 gbl03303 adclient[19085]: WARN  <fd:25 sudo(17674)> client.sudo Unexpected error in conversation: PAM_AUTH_ERR(7)

What is this error?


Answer:

If one of the password characters was either Control+c, Control+d or something that PAM can't manage when running sudo, it will return with an "Unexpected error in conversation: PAM_AUTH_ERR(7)" PAM error.

Since the user is being prompted for password when running the sudo command, it ends up error in the form of "client.sudo Unexpected error in conversation: PAM_AUTH_ERR(7)"
