[imp] hordeprefs index for using LDAP Prefs Backend

[Brian Clark]

Hello,

I am trying to get the LDAP Prefs backend working. I keep getting this 
index related error:
Warning: Undefined index: hordeprefs in 
/var/www/html/horde/lib/Prefs/ldap.php on line 323

I assume that I need an LDAP index for hordeprefs. However, I have seen 
nothing in any documentation, or on this mailing list, that says that I 
need this. I am familiar with adding indexes to LDAP, but I was simply 
unaware that one was needed. Also, I would appreciate a suggestion as to 
what type of index is necessary, such as eq, pres, or whatever.

Brian!
