IBM AIX: smbc fails to mount a share due to krb5_init_context error 74

Troubleshooting


Problem

The AIX SMB client fails to mount an SMB share.

Symptom

Syslog logs these user.debug error messages.
user:debug smbcd: smbfsd_kerberos_begin: krb5_init_context = 74
user:debug smbcd: smbfsd_kinit:smbfsd_kerberos_begin = 74
user:debug smbcd: smbfsd_perform_krb_authentication: smbfsd_kinit = 74
user:debug smbcd: smbfs2gssdkinit: smbfsd_perform_krb_authentication = 74
user:debug smbcd: smbfs_gssAuthenticate: smbfs2gssdkinit 0 74

Cause

The AIX Kerberos library cannot find the /etc/krb5/krb5.conf file because the symbolic link /etc/krb5.conf is missing.

Resolving The Problem

Create or replace /etc/krb5.conf with a symbolic link to /etc/krb5/krb5.conf.
ln -sf /etc/krb5/krb5.conf /etc/krb5.conf
