+ * qrsh failed: No such file or directory
+If your qrsh session is not working properly and gives this error:
+
+    qrsh -verbose -l hostname=koala hostname
+    Your job 6617000 ("hostname") has been submitted
+    waiting for interactive job to be scheduled ...
+    Your interactive job 6617000 has been successfully scheduled.
+    Establishing /usr/bin/ssh session to host koala.cluster.loc ...
+    qrsh_starter: executing child process (null) failed: No such file or directory
+    /usr/bin/ssh exited with exit code 0
+    reading exit code from shepherd ... 1
+
+When we add the optoin -noshell the qrsh command will run:
+
+    qrsh -noshell -verbose -l hostname=koala hostname
+    Your job 6617014 ("hostname") has been submitted
+    waiting for interactive job to be scheduled ...
+    Your interactive job 6617014 has been successfully scheduled.
+    Establishing /usr/bin/ssh session to host koala.cluster.loc ...
+    koala
+    /usr/bin/ssh exited with exit code 0
+    reading exit code from shepherd ... 0
+
+The failed: No such file or directory, is caused by the LDAP not having a default shell set.
+The LDAP server is in our case a Windows ADS 2008 server and there is no attribute default shell.
+The solution is simple set in the nslcd.conf file the attribute loginshell: 
+
+    filter passwd (&(objectClass=user)(!(objectClass=computer))(uidNumber=*)(unixHomeDirectory=*))
+    map passwd uid sAMAccountName
+    map passwd uidnumber uidNumber
+    map passwd homedirectory unixHomeDirectory
+    map passwd loginshell "/bin/bash"
+    map passwd gecos displayName
+    filter shadow (&(objectClass=user)(!(objectClass=computer))(uidNumber=*)(unixHomeDirectory=*))
+    map shadow uid sAMAccountName
+    filter group (&(objectClass=group)(gidNumber=*))
+
