Mokey fails to start: "Encoding_Error"

[blasphemite]

mokey --debug server is met with:

INFO[0000] Using template dir: /usr/share/mokey/templates
FATA[0133] [Root cause: Encoding_Error] Encoding_Error: AS Exchange Error: failed to process the AS_REP < Encoding_Error: failed to unmarshal KDC's reply: asn1: syntax error: sequence truncated

I've recreated the keytab & still get the same error. Running klist -kt /etc/mokey/mokeyapp.keytab -e seems to run without errors:

Keytab name: FILE:/etc/mokey/mokeyapp.keytab

The mokeyapp user is a member of the "Mokey User Manager" role, which possesses the "User Administrators" privilege. Not sure what I'm missing -- any assistance is appreciated.

@blasphemite Can you provide some more details.. what version of mokey, FreeIPA? What version/flavor of Linux are you running?

[blasphemite]

Centos 8 FreeIPA 4.9.6 mokey v0.5.6 installed via rpm

edit: Attempted with Centos 7 & identical config and receive the same error

[blasphemite]

I created a new FreeIPA server to test this, and now I'm no longer getting this error. I'm thinking that's indicative of what's causing the problem, so I'll close this issue now. I'll edit in an update if I'm able to figure out the root cause.

@blasphemite Glad to hear it's working for you. Thanks for reporting back.
