Did the credential cache file get created? Strange that we do not see an open or create avc here? Upon logging in as 'rmk': rmk@flint:[~]:<1045> kinit -f Password for rmk.ORG.UK: rmk@flint:[~]:<1046> krsh -f rmk-PC This rlogin session is encrypting all data transmissions.

SELinux is preventing /usr/kerberos/sbin/login.krb5 from read, write access on the file krb5cc_p32165. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that login.krb5 should be allowed read write access on the krb5cc_p32165 file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep login.krb5 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:remote_login_t:s0-s0:c0.c1023 Target Context unconfined_u:object_r:user_tmp_t:s0 Target Objects krb5cc_p32165 [ file ] Source login.krb5 Source Path /usr/kerberos/sbin/login.krb5 Port <Unknown> Host (removed) Source RPM Packages krb5-appl-servers-1.0.1-3.fc14.1 Target RPM Packages Policy RPM selinux-policy-3.9.7-31.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.37.3+ #1 SMP Tue Mar 8 20:44:41 GMT 2011 i686 i686 Alert Count 1 First Seen Fri 11 Mar 2011 08:33:57 AM GMT Last Seen Fri 11 Mar 2011 08:33:57 AM GMT Local ID b6dedb78-101d-468e-b6c6-7b3a78bbb35e Raw Audit Messages type=AVC msg=audit(1299832437.565:24977): avc: denied { read write } for pid=32165 comm="login.krb5" name="krb5cc_p32165" dev=sda5 ino=9723 scontext=system_u:system_r:remote_login_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_tmp_t:s0 tclass=file type=SYSCALL msg=audit(1299832437.565:24977): arch=i386 syscall=open success=no exit=EACCES a0=b9373498 a1=2 a2=bf9f9e28 a3=2 items=0 ppid=32163 pid=32165 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=19 comm=login.krb5 exe=/usr/kerberos/sbin/login.krb5 subj=system_u:system_r:remote_login_t:s0-s0:c0.c1023 key=(null) Hash: login.krb5,remote_login_t,user_tmp_t,file,read,write audit2allow #============= remote_login_t ============== allow remote_login_t user_tmp_t:file { read write }; audit2allow -R #============= remote_login_t ============== allow remote_login_t user_tmp_t:file { read write };
