Hi again everyone, It turns out this issue was related to quoting I had literally -f '(&(uid=%u)(memberof=cn=%g,ou=groups,ou=people,dc=cms,dc=waikato,dc=ac,dc=nz))' But when I looked in cache.log this was reported as group filter ''(&(uid=clintd)(memberof=cn=mysql,ou=groups,ou=people,dc=cms,dc=waikato,dc=ac,dc=nz))'', searchbase 'ou=People,dc=cms,dc=waikato,dc=ac,dc=nz' squid_ldap_group WARNING, LDAP search error 'Bad search filter' Removing the single quotes fixes the issue Connected OK group filter '(&(uid=clintd)(memberof=cn=mysql,ou=groups,ou=people,dc=cms,dc=waikato,dc=ac,dc=nz))', searchbase 'ou=People,dc=cms,dc=waikato,dc=ac,dc=nz' Thank you to Amos Jeffries for the pointer to cache.log On Thu, Mar 10, 2011 at 1:29 PM, Clint Dilks <clintd@xxxxxxxxxxxxx> wrote: > Hi Everyone > > I am encountering an issue with this module which I don't understand. >
