[gssproxy] gssproxy stopped working for apache

[Rob Verduijn]

Hello all,

I've got this weird problem.

I have a server that uses kerberized mounts.

One service (squeezebox) uses a mount point and is able to access it using
gssproxy.
But the other service (apache) is not able to access it using gssproxy.

This is my gssproxy.conf
[gssproxy]

[service/squeezebox]
  mechs = krb5
  cred_store = ccache:FILE:/var/lib/gssproxy/clients/krb5cc_squeezebox
  cred_store = client_keytab:/etc/gssproxy/clients/squeezbox.keytab
  cred_usage = initiate
  euid = 997

[service/apache]
  mechs = krb5
  cred_store = ccache:FILE:/var/lib/gssproxy/clients/krb5cc_apache
  cred_store = client_keytab:/etc/gssproxy/clients/httpd.keytab
  cred_usage = initiate
  euid = 48

And I triple checked the apache principal, it is definitely the right one.


I see this in the logs for the working service :
Client connected (fd = 10) (pid = 1625) (uid = 997) (gid = 997) (context
=ystem_u:system_r:gssd_t:s0)
gp_rpc_execute: executing 6 (GSSX_ACQUIRE_CRED) for service "squeezebox",
euid: 997, socket: (null)
gp_rpc_execute: executing 8 (GSSX_INIT_SEC_CONTEXT) for service
"squeezebox", euid: 997, socket: (null)
gp_rpc_execute: executing 8 (GSSX_INIT_SEC_CONTEXT) for service
"squeezebox", euid: 997, socket: (null)

a\but the apache service gives me:
Client connected (fd = 10) (pid = 1695) (uid = 48) (gid = 48) (context =
system_u:system_r:gssd_t:s0)
gp_rpc_execute: executing 6 (GSSX_ACQUIRE_CRED) for service "apache", euid:
48, socket: (null)
Client connected (fd = 10) (pid = 1696) (uid = 48) (gid = 48) (context =
system_u:system_r:gssd_t:s0)
gp_rpc_execute: executing 6 (GSSX_ACQUIRE_CRED) for service "apache", euid:
48, socket: (null)
Client connected (fd = 10) (pid = 1698) (uid = 48) (gid = 48) (context =
system_u:system_r:gssd_t:s0)
gp_rpc_execute: executing 6 (GSSX_ACQUIRE_CRED) for service "apache", euid:
48, socket: (null)
Client connected (fd = 10) (pid = 1699) (uid = 48) (gid = 48) (context =
system_u:system_r:gssd_t:s0)
gp_rpc_execute: executing 6 (GSSX_ACQUIRE_CRED) for service "apache", euid:
48, socket: (null)

Any ideas on what is causing the gssproxy to fail for apache ?
