Ex-windows admin wrapping my head around PAM/SSSD has been quite tough!
I have successfully managed to to get pam_sss working with
login for specific appliction rstudio server (/etc/pam.d/rstudio)
containerized ubuntu
ldap/krb5 auth
against Microsoft Active Directory
without domain join realmd. (so all hand-configured. ouch)
the problem is with reuse of the ticket. i cant work out how it works..
I would like to configure pam_mount and ODBC to use the same kerberos ticket that was
generated by the pam_sss modules
so
pam_sss creates a ticket with the follwoing naming which cannot be used by the
"mount" command:
/tmp/krb5cc_uid_xxxx
however if i manually use kinit, it creates a ticket with the naming below, which can be
easily reuse from the "mount" command:
/tmp/krb5cc_uid
the naming that pam_sss uses seems to be standard but again i just cant work out how that
should be "discoverable" by any other services looking for a ticket, when it has
the wrong naming..
Hi,
if the only thing you need is to change a template, then please see
`man sssd-krb5 : krb5_ccname_template` option.
(I'm sorry I'm not fluent in kerberos enough to comment on other parts
of your email)
some links..:
this seems to be where the pam_sss naming is defined - by a build flag
--with-default-ccname-template
https://github.com/SSSD/sssd/blob/master/src/conf_macros.m4#L337
i want to integrate it into pam_mount to mount a cifs drive, which (i think) is SMB so
will be able to use the cifs.upcall library.
And the way cifs.upcall resolves tickets is somehwere here in
get_cachename_from_process_env
https://github.com/aaptel/cifs-utils/blob/master/cifs.upcall.c#L260
i also want to get MSSQL ODBC driver to use the ticket as well...
