I have implemented a java code which connects to the given host ip with username and password of the AD server.(using JNDI)
Now when I use a username which has no special character it works fine. But when I use symbols like $, #, &, etc in the username it gives me Auth. Error.
I am surprised to see this because &,$, and # are not used in userdn format by AD.
Can anyone explain what the problem and what can be the solution for this.
Thanks
I cannot be sure (I have very little information to judge), but there may be a problem with the "7-bit-check-plugin". It is a LDAP plugin, which is responsible for rejection of data that are coded with more than 7 bits. This includes characters as %, $, # as well as some German characters, middle and east European characters, etc.
Please try to check if you have enabled 7-bit-check-plugin. If so, try to disable it and use that data again.

Am working on anypoint studio 6.6.8 with runtime 3.9.4EE.
I have the following mssql generic database connection string.
jdbc:sqlserver://ABC.org:59000;databaseName=master;username=nrp;password=*37n%3b#wu;5r:;_1z~(f{1y{j
Test connection gives me the following error:
Test connection failed:
org.mule.module.db.internal.domain.connection.ConnectionCreationException: Cannot get connection for URL jdbc:sqlserver://ABC.org:59000;databaseName=master;username=nrp;password=<<credentials>>;5r:;_1z~(f{1y{j: The connection string contains a badly formed name or value
PS: I have 2 semi colons in password
I have seen similar question raised here earlier a few times, hence my question might look repetitive.
however I tried the following solutions given in the replies. none of them worked. Please let me know if you have any alternate solution.
Enclosing the password in single quotes.
adding \ in front of ;
Enclosing password within double quotes or {}
Am not the admin hence removing ; from password cannot be done.
The connection string is in a format known as JAVA JDBC URL. It is similar to a normal URL. Many characters are not allowed in URLs and have to be encoded with the URL encoding method. Try using URL encoding for the entire URL. You can do it with most languages or online pages, though you might want to avoid public pages for sensitive information like passwords.

Thank you #aled
So the {} did work. I was doing it the wrong way.
I was encrypting the password & later concatenating {} to the decrypted password right b4 passing the connection string.
What worked was that I enclosed the password in {} first & then encrypted it.
I'm trying to authorize a user depending on his group membership.
Apache is configured as follows:
AuthLDAPURL "ldap://DOMAIN.COM/DC=FOO,DC=COM?CN?SUB?(objectClass=user)" NONE
AuthLDAPBindDN "CN=..."
AuthLDAPBindPassword "..."
Require ldap-group CN=\#\#SOMETEXT,OU=GSI,OU=DMM,OU=DDSIS,OU=Admin_Exchange,DC=DOMAIN,DC=com
The problem comes from the two hashes that appear in the CN.
I tried with and without quotes, with two backslashes and no backslashes, URL encode, but nothing worked.
I always get the following error message.
[Thu Feb 13 18:40:56.728349 2020] [authnz_ldap:debug] [pid 17154]
mod_authnz_ldap.c(922): [client 10.255.180.148:65050] AH01719:

"CN=##SOMETEXT,OU=GSI,OU=DMM,OU=DDSIS,OU=Admin_Exchange,DC=DOMAIN,DC=com": didn't match with attr Comparison complete [member][34 - Invalid DN
syntax]
When i remove the hashes, i get a no such object error, that confirms the problem comes from the hashes.
EDIT:
As suggested in the answer, I tried to write the octal representation of the hash character \43 but it gave me the exact same error:
"CN=##SOMETEXT, ...Invalid DN syntax]
So that doesn't seem to change what Apache sends to LDAP
You typically can get around these type of issues with something like:
CN=\23\23SOMETEXT,OU=GSI,OU=DMM,OU=DDSIS,OU=Admin_Exchange,DC=DOMAIN,DC=com
As described in RFC 4514 and Characters to Escape
However, different applications may be trying to parsing these parameters for you and may interfere with the escaping process.
The RIGHT thing to do is rename the group.
The problem you are encountering will persist with other application in the future. Best Practices for LDAP imply all Relative Distinguished Names be "URL Safe" and not require escaping.
You will need to escape the string according to RFC 4515 String Representation of Search Filters
Generally, you need to escape the items listed in RFC 4515 String Representation of Search Filters and I would suggest, also any non-UTF8 character.
I also found some methods that may be helpful to get you started.
I believe the proper escaped value you are trying to find is: All in 463"567y\5c22"\c2\a4&/2#%&! Test Group
Finally, quit it. Start populating a searching for Description or some other non-naming attribute. (any attribute that is not part of the DN) Make your DNs never changing. No user should ever see a DN which should be only a path to an entry. You will have issues with many "off-the-shelve" tools if you continue this practice.
I tried and was not even able to create an entry in two different vendors' tools.
I am unable to connect with database using psycopg2 module. This may be due to the # character needing escaping, but I have already tried this. Also, it could be related to my password having the "/" character, or the hostname having the "-" character, and I don't know how to escape it (I've already tried escaping using %2f and %2D).
This is the code I have tried with a edited password, so you can see the "special" characters it has, and also the "-" characters in the hostname. Most likely I am doing this wrong.
engine = create_engine('postgresql://username:asd/32foo/T123%40sql-is-a232#sql-is-a232.database.windows.net:5432/database')
The username here is: username,
The password here is: asd/32foo/T123,
The hostame (I think this is) here is: sql-is-a232,
The server here is: sql-is-a232.database.windows.net,
The database name here is: database.
Any help would be greatly appreciated!
Please reference this document: Database Urls:
As the URL is like any other URL, special characters such as those that may be used in the password need to be URL encoded. Below is an example of a URL that includes the password "kx%jj5/g":
postgresql+pg8000://dbuser:kx%25jj5%2Fg#pghost10/appdb
The encoding for the above password can be generated using urllib:
>>> import urllib.parse
>>> urllib.parse.quote_plus("kx%jj5/g")
'kx%25jj5%2Fg'
Examples for common connection styles follow below. For a full index of detailed information on all included dialects as well as links to third-party dialects, see Dialects.
Hope this helps.
When attempting an ldapmodify to set the unicode password (with the correct encoding) over SSL(636), the operation fails and Active Directory returns the following error code:
0000052D: SvcErr: DSID-031A1248, problem 5003 (WILL_NOT_PERFORM), data
0
I found countless threads and answers on resolving WILL_NOT_PERFORM but I am hoping someone knows the meaning of the exact codes above.
Every other solution points to password complexity, min pw age before the modify, SSL requirement, encoding requirement, and some others.
We have set the min pw age to 0, ensured we met the pw complexity requirements, encoded in UTF16LE=>base64, submitted the operation over SSL with 256 bit encryption and trusted/verified certificates, and we still receive this message.
The ldapadds/modifies are being performed by an automated tool which has successfully worked on other AD 2008 R2 instances so we know the password reqs, encodings, and SSL requirements are satisfied by the tool. We also tested with manual ldapmodify via LDIF and receive the same message.
Can anyone shed some light on any other possible permission, bug, UAC related setting, or way to decrypt the exact error code above?
Any help would be greatly appreciated! :)
I could only guess about your environment setup, but try to perform these steps:
Check if this password really could be setup through AD interface on server
Ensure you wrap you password with double quotes before encoding (i.e. it should be "password", not password
Check if you use unicodePwd attribute to set the password
So my ldapmodify entry to set password to StrongPassword! looks like:
dn: CN=User,CN=Users,DC=corp,DC=example,DC=org
changetype: modify
replace: unicodePwd
unicodePwd:: IgBTAHQAcgBvAG4AZwBQAGEAcwBzAHcAbwByAGQAIQAiAA==
Note unicodePwd has two colons
In Gforge, when a new user tries to log in; the user is automatically registered by fetching data from LDAP. It works fine for other users but one particular user is not able to log in and gets the error LDAP Authentication failed: Invalid Credentials . I don't understand what could be the issue? Could you please help?
This is the search function I am using.
ldap_bind($ldap, $dn, $pw)
$dn = ldap_get_dn($ldap, $entry);
$entry = ldap_first_entry($ldap,$res);
$res=ldap_search($ldap, $sys_ldap_base,$sys_ldap_id_attribute . '=' . $id,
array());
If it works for some users but not for one specific user, then it's something to do with the LDAP configuration, or with the characters in that user's ID or pwd.
Is the failing user in a different org/OU? Do they have accent characters in their username or password? These things can cause compatibility issues between GForge and the LDAP server.
Does this user have a much longer user name than other users? There is a GForge config setting called "usernameregex" that governs the complexity and length of allowed user names. Even though LDAP logins result in automatic account creation, the validation of the user's unix name might fail due to the regex in place. The error noted above could certainly be the catch-all message when this happens.
The default setting is "^[a-z0-9_.-]{3,15}$". You can change the upper length limit by changing the 15 to something else. The unix_name field in the GForge database is TEXT, so it can be extremely long (1GB?).
In GForge 6.3.x and earlier, you can find that setting in /etc/gforge/gforge.conf. Change the value and then update the system using:
cd /opt/gforge/bin && php create_config_cache.php
In GForge 6.4 and later, you can use the gf-config utility to set the value. It will take effect right away:
/opt/gforge/bin/gf-config set "usernameregex" "new regex value"
