OK. As a matter of interest, some of the mkdirs executed relatively |
| 19 |
quickly - perhaps in 0.5 seconds. I never saw the screen whizzing by as |

I ought to have done, though. |

My /var is an ext3 LVM partition, doubled up on a RAID-1 disk array. In |
| 26 |
the middle of the mkdiring, I checked there were enough inodes free |

I've not got kerberos or samba installed. I appear to have ldap |
| 34 |
(whatever that might be ;-). ls -lurt /usr/bin/ldap* shows these |
| 35 |
binaries were last accessed (?used) on 2012-03-14. |

What exactly do you mean by "single-signon"? |
