+ OS/Version: Linux
+ Status: NEW   
+ Resolution: 
+ Severity: normal

+ Summary: Mixed case fields do not show up with LDAP backend
+ 
+ Hi, in trying to get Turba to work with our existing LDAP schema, we discovered
+ that only certain fields were displayed.  It turned out that fields whose name
+ was all lowercase, such as 'mobile', would display, and those with mixed case,
+ such as 'facsimileTelephoneNumber', did not.  We had a mapping like this (from
+ sources.php):
+ 
+         'fax' => 'facsimileTelephoneNumber',
+         'cellPhone' => 'mobile'
+ 
+ We traced this to turba/lib/Driver/ldap.php, getResults function:  This recieves
+ a list of attributes from the LDAP server, obtained using 
+ ldap_get_entries.  The documentation for ldap_get_entries says:
+ 
+ 'The attribute index is converted to lowercase. (Attributes are case-insensitive
+ for directory servers, but not when used as array indices.) '
+ 
+ But getResults does not take that fact into account and tries to compare with
+ the user-entered value from sources.php without converting it to lowercase. 
+ Judging by the mailing list archives, we are not the first to see this problem.
