Traceback (most recent call last):
line 685, in authenticate
group_names = self.get_member_of(con, user_data)
line 571, in get_member_of
new_groups = [x.split(',').split('=') for x in member_of]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 15:
ordinal not in range(128)
What operating system are you using? What browser?
Server is running on
Linux <confidential_hostname> 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8
19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Server version: Apache/2.4.7 (Ubuntu)
Server built: Jul 22 2014 14:36:38
The issue is browser-independent.
Please provide any additional information below.
Tried to set LANG environment variable to en_US.UTF-8 in
/etc/apache2/envvars but it didn't help.
When the exception is caught for the problematic group the log-in is
successful, but if the required group contains non-ascii characters this
solution is not enough.
Please check this.
