Hello,

we use an LDAP authentication scheme on our servers at GES DISC NASA GSFC to authenticate data access. We discovered that some wget versions do not correctly pass credentials to the LDAP server. To our knowledge wget 1.12 and lower as well as wget 1.17 do not work as expected and wget 1.14, 1.15 and 1.18 work.

I will greatly appreciate if you could look into this and see if you correct issue in wget past 1.14 as we advise to our users to download wget 1.14 and higher.

To replicate the issue just follow three steps on http://disc.sci.gsfc.nasa.gov/registration

A sample URL to try after above steps are performed is:

wget --content-disposition --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --keep-session-cookies "http://acdisc-ts1.gesdisc.eosdis.nasa.gov/daac-bin/OTF/HTTP_services.cgi?FILENAME=%2Fdata%2Fs4pa%2FAura_OMI_Level2G%2FOMTO3G.003%2F2005%2FOMI-Aura_L2G-OMTO3G_2005m0101_v003-2012m0404t152005.he5&FORMAT=SERGLw&BBOX=0%2C-100%2C90%2C180&LABEL=OMI-Aura_L2G-OMTO3G_2005m0101_v003-2012m0404t152005.SUB.he5&SHORTNAME=OMTO3G&SERVICE=SUBSET_HE5&VERSION=1.02&DATASET_VERSION=003&VARIABLES=ColumnAmountO3";

I greatly appreciate you efforts!

Irina
