Thanks Michael, I'm glad to see that this change made its way into mainline after all! Would you

good morning, We belong to PSA Peugeot Citroen Company and we need to install SAMBA on OS AIX5.3 with LDAP access. We download the SAMBA binaries 3.0.21 but in this version, we could not find the libraries for LDAP ACCESS. Could you tell us , if we have to download another version or where we can find the library for version 3.0.21. Further more , do you know if we can find a french company

Hi, I?m trying to replace some SAS statistical functions by R (batch calling). But I?ve seen that calling R in a batch mode (under Unix) takes about 2or 3 times more than SAS software. So it?s a great problem of performance for me. Here is an extract of the calculation: stoutput<-file("res_oneWayAnova.dat","w"); cat("Param|F|Prob",file=stoutput,"\n");
