I'm using automounted home directories with autofs and NFS, and the /etc/auto.home file does an ldap search to find where to mount the user's home directory from. I'm using Fedora 15 Beta. This error seems to happen occasionally until I followed the steps to fix it: SELinux is preventing /usr/bin/ldapsearch from 'read' accesses on the lnk_file /usr/tmp. ***** Plugin catchall_labels (83.8 confidence) suggests ******************** If you want to allow ldapsearch to have read access on the tmp lnk_file Then you need to change the label on /usr/tmp Do # semanage fcontext -a -t FILE_TYPE '/usr/tmp' where FILE_TYPE is one of the following: locale_t, etc_t, proc_t, automount_t, sysfs_t, var_run_t, abrt_t, lib_t, root_t, proc_net_t, device_t, samba_var_t, ld_so_t, proc_t, textrel_shlib_t, etc_runtime_t, rpm_script_tmp_t, udev_var_run_t, var_run_t, bin_t, cert_t, autofs_t, device_t, devlog_t, var_run_t, var_run_t, var_run_t, cert_t. Then execute: restorecon -v '/usr/tmp' ***** Plugin catchall (17.1 confidence) suggests *************************** If you believe that ldapsearch should be allowed read access on the tmp lnk_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 ldapsearch /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:automount_t:s0 Target Context system_u:object_r:usr_t:s0 Target Objects /usr/tmp [ lnk_file ] Source ldapsearch Source Path /usr/bin/ldapsearch Port <Unknown> Host (removed) Source RPM Packages openldap-clients-2.4.24-2.fc15 Target RPM Packages filesystem-2.4.40-1.fc15 Policy RPM selinux-policy-3.9.16-13.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux sjera.tcct.nmt.edu 2.6.38.2-9.fc15.x86_64 #1 SMP Wed Mar 30 16:55:57 UTC 2011 x86_64 x86_64 Alert Count 55 First Seen Wed 18 May 2011 05:16:42 PM MDT Last Seen Thu 19 May 2011 01:41:25 PM MDT Local ID e911d322-b470-4525-81e4-54fd24298d94 Raw Audit Messages type=AVC msg=audit(1305834085.680:130): avc: denied { read } for pid=4239 comm="ldapsearch" name="tmp" dev=dm-1 ino=132135 scontext=system_u:system_r:automount_t:s0 tcontext=system_u:object_r:usr_t:s0 tclass=lnk_file type=SYSCALL msg=audit(1305834085.680:130): arch=x86_64 syscall=stat success=no exit=EACCES a0=3300a419a3 a1=7fff5baac780 a2=7fff5baac780 a3=0 items=0 ppid=4238 pid=4239 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=ldapsearch exe=/usr/bin/ldapsearch subj=system_u:system_r:automount_t:s0 key=(null) Hash: ldapsearch,automount_t,usr_t,lnk_file,read audit2allow #============= automount_t ============== #!!!!
